If one knows how to read between the lines, then at this lecture you finally can hear what, in different words, could well be re-phrased as: the search for M-theory using dualities failed. [Slides], Thorsten Schimannek (LPTHE Paris) But what DUNE will find has been predicted years ago: normal neutrino mass order, no additional neutrinos, no proton decay, and no physics beyond the standard model whatsoever. Making statements based on opinion; back them up with references or personal experience. Yes, but I cant imagine that Witten was thinking of anything as well known and well understood as a qubit. CRM, Montreal, Canada. Thank you. Title: Langlands duality for 3-manifolds Philip Candelas Sen is saying hell give up on string theory if people prove that string theory is inconsistent, but Minwalla and Witten are saying there is no definition of the term string theory. Announcement String Math 2022 Lorenz Eberhard(IAS) String correlators on AdS3 17:00 - 17:50 14:00 - 14:50 Melissa Liu(Columbia University) Wall-Crossing for the Mirror Quintic . In this talk, I will present a match between the large-N saddles of the correlation functions of determinants with semiclassical D-brane configurations in the dual theory, using a spectral curve construction. Title: Vafa-Witten Theory: Invariants, Floer Homologies, Higgs Bundles, a Geometric Langlands Correspondence, and Categorification [online talk] Our starting point will be the observation that a rich source of discrete gauge symmetries in M-theory are Calabi-Yau threefolds with singularities that cannot be crepantly resolved. We can exhibit for instance a duality between a trivial bundle with abelian isometries and a non-trivial *bibundle* with a nonabelian Poisson-Lie group action. with the exact opposite agenda. UBC, Vancouver, Canada. Piotr Sukowski (chair) A limit involving the quotient of two sums. for Fundamental Research), [D] Juan Maldacena (Institute for Advanced Study), [T] Shiraz Minwalla (Tata Inst. Not all N = (0, 4) boundary conditions admit such deformations. Correlation functions in the worldsheet theory on AdS_3 are shown to agree with those of the dual CFT_2, with both being given in terms of branched covers. Abstract: I will be discussing my recent work [2110.08179] with Chris Blair and Dan Thompson on topology change in Poisson-Lie T-duality with spectators (i.e. Lakshya Bhardwaj (University of Oxford) [Slides] [Video], Sunghyuk Park (California Institute of Technology) Is there a way to calculate a formula stored in a string in JavaScript without using eval()? that perturbation series following from superstring S-matrix, already known to diverge as one sums over all moduli parameters (which isnt really the issue, since this happens even in QED, see Dyson, F.J., 1952. StringBufferStringBuilder 1. One reason for this being a real mistake is that, divorced from input from the real world, theory becomes sterile: Questions Posed by Nature are Vastly Deeper and more fruitful than ones we humans tend to pose for ourselves. I think a better service to the public would be made by discussing things that are well established, rather that the permanent focus on what is coming/the future etc. We present a novel construction of such flux vacua in permutation-symmetric multiparameter compactifications, and develop methods for efficiently computing the zeta functions of the corresponding geometries. Abstract: I will explain how to construct BPS algebras for string theory on general toric Calabi-Yau threefolds, based on the crystal melting description of the BPS sectors. We also provide the action of braiding on the relevant branes, so we can calculate Khovanov homology for any knot given its braid representation. Ill explain this phenomenon, and propose a new effective algorithm for the calculation of the spectrum which is not based on quantum algebra at all (joint work in progress with A. Soibelman). Marlborough School. [Slides], Meng-Chwan Tan (National University of Singapore) Rio de Janeiro, June 18th, 2021. Abstract: We implement the unitary equivalence of modular Hamiltonian $hat{H}_{mathrm{mod}}$ and Hamiltonian $hat{H}$,$hat{H}simhat{U}^{dagger}hat{H}_{mathrm{mod}}hat{U}$, to realize the emergence of time from an unitary operator $hat{U}$. Its very good but he often leaves the reader a lot to figure out. I will also discuss a second application, a new definition of FJRW invariants in the presence of an arbitrary symmetry group. Connect and share knowledge within a single location that is structured and easy to search. Everything is in the description. IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online eventSpeaker: Giovanni Felder (ETH Zrich)Lecture title: Superstring measure and the superper. It seems that non-stringy approaches to quantum gravity are not very successful at reproducing these universal results. We physically derive (i) a novel Vafa-Witten four-manifold invariant associated with this moduli space, (ii) their relation to Gromov-Witten invariants, (iii) a novel Vafa-Witten Floer homology assigned to three-manifold boundaries, (iv) a novel Vafa-Witten Atiyah-Floer correspondence, (v) a proof and generalization of a conjecture by Abouzaid-Manolescu about the hypercohomology of a perverse sheaf of vanishing cycles, (vi) a Langlands duality of these invariants, Floer homologies and hypercohomology, and (vii) a quantum geometric Langlands correspondence with purely imaginary parameter that specializes to the classical correspondence in the zero-coupling limit, where Higgs bundles feature in (ii), (iv), (vi) and (vii). This is a joint work with K. Ohmori (U. Tokyo). with the exact opposite agenda.. Hello, Robert A. Wilson We also discuss generalizations to b_2^+(X)>1. In the present talk we show that the string theory duals of these systems are classically integrable. A place where magic is studied and practiced? Abstract: Three-dimensional N =4 supersymmetric field theories admit a natural class of chiral half-BPS boundary conditions that preserve N = (0, 4) supersymmetry. Recently, a rigorous probabilistic construction of the path integral was provided using the Gaussian Free Field. rotations and translations are typically discretized due to the presence of a lattice)? Weekly on Mondays 2:10 PM (Pacific Time) Meetings are in-person, at 402 Physics South. Additionally, Evaluator.js intelligently reports invalid syntax, such as a misused operator, missing operand, or mismatched parentheses. Number Strings & Math Talk Routines for Grades 3-5. In response to the obvious question about relation to experiment and testability, people have clearly completely given up on this, with nothing to say (other than a bogus claim that string theory makes some prediction about B-mode polarization), going on about how it took thousands of years for the atomic hypothesis to be vindicated. TheAttractor Flow Tree conjecture postulates that the BPS index $\Omega(\gamma,z)$ for given charge $\gamma$and moduli $z$ can be reconstructed from the`attractor indices $\Omega_*(\gamma_i)$ counting BPS states of charge $\gamma_i$ in their respective attractor chamber, by summing over all possible decompositions $\gamma=\sum_i \gamma_i$ and over decorated rooted flow trees. So, does anyone know about alternatives to eval()? Maxim Kontsevich (IHS) LQG calculations claim to reproduce the semi-classical limit. There will also be a public lecture and outreach activity Ask a String Theorist during the weekend. Nigel Hitchin (University of Oxford) Our brane engineering approach combines the intersecting brane configurations of HananyWitten with recent work of Costello and Li on twisted supergravity. How is Jesus " " (Luke 1:32 NAS28) different from a prophet (, Luke 1:76 NAS28)? When the quiver comes from a smooth local toric Calabi-Yau 3-fold, we obtain a generalization of shifted Yangian, which acts on the cohomology of the moduli space of certain sheaves of the 3-fold. Abstract: The sphere packing problem is a very natural geometric question and it has a long and exciting history. Boris Pioline (Universit Pierre et Marie Curie) We focus on $\hat Z$ for $SO(3)$ group and orthosymplectic supergroup $OSP(1|2)$. How to evaluate string mathematical expressions in java script? Organized by Mina Aganagic , Ivan Danilenko , Andrei Okounkov, and Peng Zhou. String Math 2021 IMPA, Rio de Janeiro, June 14 - 18 Program Break. I hadn't known about this until your post. [Slides] [Video], Davide Gaiotto (Perimeter Institute) He never actually gets anywhere near discussing the topic of the title for the talks, but does give a very nice leisurely introduction to computing amplitudes for zero-mass particles. This construction gives rise to new quantum groups. [Slides], Ioannis Lavdas (LMU Munich) lun, We prove a reformulation of the main conjecture in Fukayas second correspondence, where multi-valued Morse theory on the base B is replaced by tropical geometry on the Legendre dual B. Nothing will be said about multiverses or swampland on what follows. I will then outline work in progress with Gunningham and Safronov to prove the conjecture in a number of special cases. Abstract: Gross and Siebert developed a program for understanding mirror symmetry algebro-geometrically. You can sanitize the string with a regex first to be safe: If you wanted another method, you'd have to use a pure Javascript implementation of the exact thing eval is going to do. I will also touch upon the issue of the Lorentzian vs Euclidean metric slice in the path integral contour of quantum gravity. Another series of talks that I took a look at and that I can recommend is Nima Arkani-Hameds lectures on Physics at Future Colliders at the ICTP summer school on particle physics. Jackiw-Teitelboim/PeterH, If you are interested in what field theories Wittens probably interested in, then I certainly recommend you to follow the on going ICTSs Quantum Field Theory, Geometry and Representation Theory, with Wittens mini-course starting tomorrow: https://www.icts.res.in/program/qftgrt2021/talks, In order to get a feel what is at stake here, start with: Math 250 (Vector Analysis) . In 2019, S. Gukov and C. Manolescu initiated a program to mathematically construct via Dehn surgery, and as part of that they conjectured that the Melvin-Morton-Rozansky expansion of the colored Jones polynomials can be re-summed into a two-variable series for knot complements. From this description, we propose a symmetry for the space of instantons on C^2 by an exceptional super Lie algebra called E(3|6). Hope you will find them as a useful starting point. Solutions to this system describe compactifications of heterotic string theory with N=1 supersymmetry on a 7-dimensional manifold. Title: Perturbative calculations in twisted 4d gauge theories [online talk] Paul-Konstantin Oehlmann (Uppsala University) Rafa R. Suszek, Louis Alvarez-Gaume Finally, we will talk about the connections between the sphere packing problem and some mysteries of modern physics. The operators satisfy an operator product expansion. We highlight prototype examples of elliptically fibered non-compact Calabi-Yau fewfolds and comment on the fate of these symmetries when these spaces become compact. This jargon sounds a bit confusing. lectures on Physics at Future Colliders at the ICTP summer school on particle physics, talk on Connecting String Theory to the Real World We See Outside Our Windows, https://sites.google.com/unifi.it/scri21/program, https://www.youtube.com/watch?v=WwmxaXTnGMI, https://www.youtube.com/watch?v=hk_6EtWUatM. How do I replace all occurrences of a string in JavaScript? +1 upvote from me, and I've already used it in a project. Title: Knizhnik-Zamolodchikov revisited: (non)supersymmetric gauge theories, defects, and localization Title: Holomorphic boundary conditions for topological field theories via branes in twisted supergravity I will discussa phenomenon similar to Frobenius of modular representation theory. Considering two heterotic E8 E8 and Spin(32)/Z2 string theory placed on various background singularities, we expect the heterotic NS5 instantons to fraction. In this talk, I will construct a large class of discrete geometric structures in all dimensions that satisfy these two properties, using the theory of hyperbolic buildings. On the other hand, differential cohomology theories, whose relationships with physics are classical, are most modernly understood in terms of sheaves on manifolds with values in (\infty, 1)-categories. A ternary string is a sequence of n symbols that has some of the digits 0, 1, 2. Enjoy, This solution also clips whitespaces and checks for duplicating operators, e.g. ' Abstract: Twisted holography relates the 2d chiral algebra subsector of N = 4 SYM to the B-model topological string theory on the deformed conifold SL(2,C). This is based on arXiv:2202.01788, with Matilde Marcolli and Sarthak Parikh. Abstract: Recently there has been lots of activity surrounding generalized notions of symmetry in quantum field theory, including categorical symmetries, higher symmetries, noninvertible symmetries, etc. Besides reviews of major developments in the field and specialized talks on specific topics, an important novelty will be several informal discussions involving two researchers and the conference participants. IMPA, Rio de Janeiro, June 14 18, 2021 Turned into an online event. 10. Abstract: We revisit Vafa-Witten theory in the more general setting whereby the underlying moduli space is not that of instantons, but of the full Vafa-Witten equations. It is expected that the right mathematical structure to capture physical properties of such symmetries is that of higher-categories. Even beginning PhD students will no longer believe that ST is the only framework that reproduces BH entropy. StringStringBuilderStringBufferMath. Tony Pantev Adrian Langer Whats really bizarre about the current situation is that string theory has completely decoupled from any well-defined proposal for an actual 3+1 d unified theory of gravity and the SM, while at the same time its proponents claim it is the only game in town. Even beginning PhD students will no longer believe that ST is the only framework that reproduces BH entropy. (UoS & CNRS) Quantum G & of Looijenga pairs Berkeley String-Math 2021 Overview The two main messages: 1ve (different, but equivalent) string-theory motivated enumerative theories built from (X;D) 2they are all closed-form solvable Joint with P. Bousseau (ETH Zrich/Saclay) and M. van Garrel (Warwick/Birmingham). These symmetries vastly generalize the standard notion of global symmetries, and can be used in a similar way to obtain insights into strongly-coupled physical phenomena. Dec 18, 2021 at 16:43. Adrian, Condensed matter physics is a quite different story. String theorists are for the most part no longer actively pursuing connecting to particle physics of the real world. Title: Magnetic quivers for Superconformal Field Theories String theory calculations that can be done in unphysical situations (wrong dimension, lots of SUSY, extremal black holes) claim to reproduce the semiclassical limit. In this case, because the string is assumed to be safe and trusted, we would expect use of either eval() or the Function constructor to be reasonable. and finally I published a package on npm string-math. The resulting quiver Yangians, together with their trigonometric and elliptic versions, unify various known results and generalize them to a much larger class. Strings provided the authors with a way to make relatively small changes to guided notes in algebra 1, algebra 2, precalculus, and AP calculus classes. Strings 2021 is an annual conference that brings together the entire string theory community. During professional development, the authors learned about strings--a powerful instructional routine used in elementary classrooms to elicit students' mental mathematics strategies and use those strategies to build conceptual understanding. It would differ in rare case, if this function evil() itself declared some variables which would want to be. TheamplituhedronAn,k,m(Z)is the image of the positive Grassmannian Grk,n0under a positive linear mapRnRk+m. Abstract: During my presentation, I will discuss certain equivalences between conformal field theories with a continuous spectrum: Liouville theory, its supersymmetric extension, and models based on the affine su(2) algebra with irrational level. To address the problem of quantization of a space with gauge fields, first the structure that in the smooth (i.e. [Slides] [Video], Lauren Williams (Harvard University) These operators are interesting for several reasons: Title: Calculating Quantum Knot Homology from Homological Mirror Symmetry I strongly disagree with you about the issue of the intellectual honesty of my account of what Witten and Arkani-Hamed had to say. Quantum gravity: String theory is a theory of quantum gravity because it attempts to merge quantum physics with the theory of general relativity. Title: Revisiting Heterotic ALE Instantons: F-theory, 2-groups, and T-duality I will present a rigorous version of this formula in the context of quivers with potential, which governs the BPS spectrum in type IIA string theory compactified on certain conical Calabi-Yau threefolds, in the vicinity of orbifold-type points in Kahler moduli space. We will focus on understanding 3d mirror symmetry viachiralalgebras. Certain reformulations and consequences of cosmic censorship, however, may be true in asymptotically AdS solutions that admit a consistent holographic dual. [Slides]. The simplest example is the qubit. [Slides], Alex S. Arvanitakis (Vrije Universiteit Brussel) String Math 2021, held online by IMPA, Rio de Janeiro, Rio de Janeiro, June 14 - 18, 2021. The two domain wall systems are thought to be integrable; the evidence comes mainly from the study of correlation functions at weak coupling. We hereby certify that, Alex Buchel, THE UNIVERSITY OF WESTERN ONTARIO, you see Ed Witten, and then Shiraz Minwalla, basically agreeing with you. I will illustrate this construction on examples of low rank 4d N=2 SCFTs. This talk is based on joint work with Xenia de la Ossa, arXiv:2111.13221. While such boundary conditions are not compatible with topological twists, deformations that define boundary conditions for the topological theories were recently introduced by Costello and Gaiotto. Fd. Abstract: We will discuss how dualities of quantum field theories can be understood as analogous to Morita equivalences for algebras of various types. Richard Thomas Talks are available for watching every day via Youtube, links are on the main page.

Another talk of Penrose (and a conference in his honour): Likely Witten was thinking of things like the 6d (2,0) superconformal theory which has not classical limit and its construction is somewhat mysterious. At the time I drop those lines, more than 50 years from dual resonance models?, I havent found any convincingly argument. Make an operation based on string, including priority for multiplication and division with vanilla javascript and nodejs. In my talk, I will discuss the following two examples. When the cohomology theory is the Morava E-theory, we obtain a new family of quantum groups labelled by a prime number and a positive integer. Physics Meets AI, LMU Munich, September 2020. All sessions were recorded and are available at the Youtube daily links below or by clicking on the lecture in the Schedule: Strings 2021 is an annual conference that brings together the entire string theory community. Title: Quivers for 3-manifolds I believe I am not misguided. His third talk emphasizes thinking of space-time vectors as two by two matrices (see section 40.4 of my QM book). Evaluator.js is a small, zero-dependency module for evaluating mathematical expressions. from 9:30 15:00 in So Paulo (8:30 14:00 in NY, 14:30 20:00 in Paris). I am currently reading Weinbergs book to fill some holes in my knowledge. We introduce a new idea, boundary averaging, to address the question: Does averaging also work well in AdS/BCFT? The String Math series of conferences have become an important event for anyone working at the interface between mathematics and theoretical physics (string theory, quantum field theory and adjacent topics), bringing together an interdisciplinary cohort of pure mathematicians and theoretical physicists. Invertible QFTs are expected to form a sheaf of \infty-groupoids, and we apply the framework of differential cohomology to this sheaf. String Data 2020, CERN, December 2020. Math 302 (Vector Analysis and Integration on Manifolds) Spring 2021. [Slides] [Video], Andrei Caldararu (University of Wisconsin Madison) We provide new the structure that allows this, whose quantisation turns out to be lead to a multimatrix ensemble.

David Ben-Zwi [Slides], Carlos Perez-Sanchez (University of Heidelberg) Quantum physics studies the smallest objects in the universelike atoms and subatomic particleswhile general relativity typically focuses on larger-scale objects in the universe. - rgbk21. I am not a fan of string theory. This approach is based on 2105.06039 and is joint work with Aganagic and Rapcak. Leonardo Rastelli Reimundo Heluani Organizing Committee. In 2016 the speaker was lucky enough to solve the sphere packing problem in dimension 8 and contribute to its solution in dimension 24. Yuji Tachikawa Abstract: Thepositive GrassmannianGrk,n0is the subset of the real Grassmannian where all Plcker coordinates are nonnegative. (not not) operator in JavaScript? To learn more, see our tips on writing great answers. If people think carrying on this argument is a good use of their time, they are encouraged to do so elsewhere. You are either blinded or so convinced by the idea that string theory has nothing to say about Physics, that you pick any phrase that adds to your view of things. LHC will discover SUSY We construct a trace map on the elliptic chiral homology of the free beta gamma-bc system using the BV quantization framework. The talk is based on work in collaboration with Davide Gaiotto. [Slides]. ), one would at least expect that a well-behaved asymptotically perturbation series follows as one takes into account contributions from all the moduli parameters of Teichmller spaces of Riemann surfaces with higher genus and market points. The nature of simulating nature: A Q&A with IBM Quantum researcher Dr. Jamie We've added a "Necessary cookies only" option to the cookie consent popup. Update: In the final discussion section, Witten emphasizes that What is string theory? still has no answer, that we have little idea what it really is. Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2, Evaluate an Equation in Javascript, without eval(), Stand-in mathematical replacement for eval.

[Slides], Sachin Chauhan (Indian Institute of Technology, Bombay) Anyway, truly bold attempt! I think I was doing him a favor by not quoting that kind of thing, which he really should be embarrassed about. Title: Towards F-theory MSSMs You will have to use the Number.isNaN() method to do it. Add a comment | 21 . Abstract: Since 2017, knots and symmetric quivers are known to be intimately related via BPS spectra. I notice that Roger Penrose, a well-know string theory skeptic, will be giving a talk on the last day of the conference next week. The String Math series of conferences have become an important eventfor anyone working at the interface between mathematics and theoretical physics (string theory, quantum field theory and adjacent topics), bringing together an interdisciplinary cohort of pure mathematicians and theoretical physicists.
