We show that many 3d theories can be represented as plumbing graphs and hence be able to be constructed by compactifying M5-branes on corresponding plumbing manifolds using the construction of 3d-3d correspondence. Based on 2103.10271, 2111.07663 and upcoming work. 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. rev2023.3.3.43278. The talk is based on work in collaboration with Davide Gaiotto. I will show how this calculation works for su(2) and give an example. 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. Shing-Tung Yau (Harvard University), The interpretation of semiclassical gravity as an average of CFTs has provided much progress in understanding the factorization problem and the information paradox. The latter approach allows to realize holomorphically and topologically twisted field theories directly as worldvolume theories in deformed supergravity backgrounds, and we make extensive use of this. The University of Warsaw The University of Warsaw, founded in 1816, is the largest university in Poland and a leading research centre in the country and in this region of Europe. [Slides] [Video], Antoine Bourget (CEA Saclay) This includes joint work with David Ben-Zvi, David Jordan, Pavel Safronov, Monica Vazirani, and Haiping Yang. Abstract: Gross and Siebert developed a program for understanding mirror symmetry algebro-geometrically. Probably the best answer. Abstract: Knizhnik-Zamolodchikov equation, originally found in the context of a two dimensional conformal field theory, has recently been found in the context of instanton counting, albeit with a significantly extended domain of allowed parameters (level, spins etc). [Slides] [Video], Maxim Kontsevich (IHS) Black Hole Entropy and the Problem of Universality [https://arxiv.org/abs/gr-qc/0702094]. Requiring the unitary equivalence also implies Modular Chaos Bound = Chaos Bound''. 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. CEIs should be thought of as a precise realization of the general idea, due to Kontsevich, that the category of open strings (plus data of the splitting) determine closed string invariants. AP Computer Science A 2021-22. Braces are not supported, am I right? Mathematically, they can be identified with the K-theoretic versions of the Donaldson invariants on X. 2. If one neglects the mass term, they are formally homogeneous. Please, do appreciate that negative comments like yours distort the ideas the general public (or even physicists in other areas) have about String Theory, or Theoretical Physics in general. These higher-categories are constructed by equivariantizing higher-categories corresponding to invertible higher-form symmetries. How to format a number with commas as thousands separators? This story also relates to the higher-form global symmetry. [Slides] [Video], Edward Witten (IAS) Hello, Robert A. Wilson Is it possible to create a concave light? This is exactly the place where you should be using eval(), or you will have to loop through the string and generate the numbers. The match can be extended to saddles which appear in non-trivial Coulomb branch vacua. String theorist: indeed, whats QCD?. Strings 2021 will be held online during the two-week period June 21 July 2, 2021 from 9:30 15:00 in So Paulo (8:30 14:00 in NY, 14:30 20:00 in Paris). Youre right that I was cherry-picking, but in the sense of ignoring the huge amount of hype about what great progress was being made, and sticking to writing about certain places where people like Arkani-Hamed or Witten chose to address the real problems (which most of the time are studiously ignored). All major operations, constants, and methods are supported. Maxim Kontsevich (IHS) But regarding superstrings, from such a strong statement one would expect at least proof (not rigorously by mathematical standards of course!) Thanks for allowing my last comment. Asking for help, clarification, or responding to other answers. 5. In the ending remark, Ooguri makes the observation that the percentage of speakers older than him is roughly a linear function (64-2x)% where x is the number of years after his PhD. We provide significant evidence that averaging plays an important role in reproducing. [Slides], Sachin Chauhan (Indian Institute of Technology, Bombay) You, sir, are awesome. Workshop on Algebraic Geometry and Machine Learning, Tsinghua Sanya International Mathematics Forum, January 2021. We also discuss generalizations to b_2^+(X)>1. Abstract: We discuss the partition functions of topologically twisted 5d SU(2) supersymmetric Yang-Mills theory on X x S1, where X is a smooth closed four-manifold. This is a truly fundamental idea about space time geometry that gets too little attention in most physics courses. Suomynona, Title: Perturbative calculations in twisted 4d gauge theories [online talk] Strings 2021 is an annual conference that brings together the entire string theory community. What am I doing wrong here in the PlotLegends specification? Abstract: Three-dimensional N =4 supersymmetric field theories admit a natural class of chiral half-BPS boundary conditions that preserve N = (0, 4) supersymmetry. Im no whit wiser than when I began. Probably not if you ask me. W roku 2019 otrzymaa nagrod Fermata oraz nagrod Ruth Lyttle Satter przyznawan przez Amerykaskie Towarzystwo Matematyczne, a w roku 2020 nagrod Europejskiego Towarzystwa Matematycznego. More operators/functions can be easily defined with the Calculation.defineOperator method: If you don't want to use eval you will have to use an existing expression evaluator library. Strings 2021 - ICTP - SAIFR In our examples we find agreement with the flux modularity conjecture of Kachru, Nally, and Yang. Quantum gravity: String theory is a theory of quantum gravity because it attempts to merge quantum physics with the theory of general relativity. How would you please implement. General string perturbation theory using 2d conformal field theory. [Slides] [Video], Jan Dereziski (University of Warsaw) Chrome's Content Security Policy will still throw EvalError, Creating constructor doesn't make sense here and it takes unnecessary resources. The CY manifolds admitting supersymmetric flux vacua can be associated to elliptic, Hilbert, or Bianchi modular forms, depending on the field the complex structure moduli of the CY take values in. Zygmunt Lalak How useful this will be will depend on the symmetries you have available. But I believe that in todays update of this post you were not intellectually honest. In particular, we provide two different path integral derivations of their wall-crossing formula for b_2^+(X)=1. According to this philosophy, connection to particle physics appear[s] hopeless/parochial/unimportant. Title: Automorphic Spectra and the Conformal Bootstrap Our brane engineering approach combines the intersecting brane configurations of HananyWitten with recent work of Costello and Li on twisted supergravity. Abstract: Recently, higher categorical understandings of quantum field theories have been rapidly developing. [Slides]. with the exact opposite agenda.. Title:Plumbing graphs with matter Reimundo Heluani Organizing Committee. . I could go on the whole night, but I believe, as most other string theorists do, there are more urgent or at least doable problems to solve now. Unit 3 - String, Math | APCS crickets]. It will often be a good idea to analyze states in terms of these irreducible representations. 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. Abstract: Holographic tensor networks are discrete models of AdS/CFT that satisfy complementary recovery of quantum information and the Ryu-Takayanagi formula, which relates the boundary entanglement entropy to the area of extremal surfaces in the bulk. 3 years ago, F_K invariants of knot complements in 3-sphere have been proposed. Title: Quantum curves and vertex algebras The quotes I gave are accurate, and links are provided so that anyone who wants to can see the full context. Title: A holomorphic approach to fivebranes Abstract: I will present some conjectures for higher-rank K-theoretic Donaldson-Thomas theory on toric three-folds, and some lessons that we learned from working equivariantly on non-compact spaces. @adrianmigueldiego: as a mathematical-physics, I have been earring for 20 years that string theory is the only game in town, I have seen the raise of LQG as an opponent to string, and I witnessed the tentative of string theory to kidnap noncommutative geometry claiming that this was nothing but the geometry of string theory. nagrod Salema, nagrod Matematycznego Instytutu Claya, nagrod New Horizons in Mathematics. Thank you. Oh, God, how hard Ive slaved away, I watched the entire video on the Poincare group and, although the path was the same as Weinberg, there was a lot of new information I thought it was excellent. Evaluator.js is a small, zero-dependency module for evaluating mathematical expressions. The way I see the string people (not necessarily those who appear in the media, but those who publish in the arXiv) is as a small set of honest and hard working physicists, technically sophisticated, researching mostly on QFT and Gravity, with various approaches. As an application, I will use conformal bootstrap techniques to obtain new rigorous bounds on the first positive Laplacian eigenvalue of hyperbolic orbifolds. Georgios Linardopoulos (Wigner Research Centre for Physics) The point though is that there are plenty of much simpler examples, which often can be understood purely in terms of representation theory. At the hand of several examples I will illustrate that this phenomenon is generic and that most Calabi-Yau threefolds admit such degenerations and a corresponding refinement of the invariants. Katrin Wendland, Ron Donagi (University of Pennsylvania) This talk is based on joint work with Xenia de la Ossa, arXiv:2111.13221. In addition, distinct tensor branch data obtained from 6D theories with a single instanton inspire us to classify heterotic strings probing ADE singularities. 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: 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 review the probabilistic construction and its equivalence with the bootstrap construction used in the physics literature. The real stuff happens in physics without a press release, book, or blog. (ii) Every-time I receive a grant report asking for resources, penned by a senior string theorist, Im already able to guess the 1st lines: ST is the only mathematically consistent candidate for understanding quantum gravity while providing a framework potentially unifying all know fundamental interactions. Piotr Sukowski (chair) Abstract: Holomorphic Floer theory is the analogof Floer theoryfor holomorphic symplectic manifolds. [Video], Hulya Arguz (IST Austria) I strongly disagree with you about the issue of the intellectual honesty of my account of what Witten and Arkani-Hamed had to say. de Lausanne), [D] Nathan Seiberg (Institute for Advanced Study), [T] Ashoke Sen (Harish-Chandra Research Institute), [R]Shu-Heng Shao (Institute for Advanced Study), [T] Yuji Tachikawa (Kavli IPMU and U of Tokyo), [T] Gregory Tarnopolsky (Carnegie MellonU), [T] Gonzalo Torroba (Centro Atmico Bariloche), [D] Edward Witten (Institute for Advanced Study), [G] Ahmadullah Zahed (Bangalore Indian Inst. String Math 2021 | IMPA - Instituto de Matemtica Pura e Aplicada To address this issue, we use the fusion-matrix bootstrap, which is recently developed in the context of the light-cone bootstrap. Richard Thomas This is a joint work with K. Ohmori (U. Tokyo). Ivan Ip's Homepage - Hong Kong University of Science and Technology [Slides] [Video], Heeyeon Kim (Rutgers University) 3. The two-step procedure involves first finding points on the Calabi-Yau manifold and then approximating the Ricci-flat metric by approximating solutions to the underlying Monge-Ampere equation. Title: Non-rational $widehat{su}(2)$ cosets and Liouville field theory Title: Liouville conformal field theory: from the probabilistic construction to the bootstrap construction Title: Holomorphic Floer theory and Donaldson-Thomas invariants Elements of this Hilbert space can be thought of as local operators living in a (d-1)-dimensional spacetime. There is also an open source implementation on GitHub, evaluator.js, and an NPM package.
