How to format a number with commas as thousands separators? The resulting quiver Yangians, together with their trigonometric and elliptic versions, unify various known results and generalize them to a much larger class. 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. 11. 1. TheamplituhedronAn,k,m(Z)is the image of the positive Grassmannian Grk,n0under a positive linear mapRnRk+m. Abstract: Currently, there is a strong interest in the study of non-invertible symmetries of quantum field theories. A place where magic is studied and practiced? StringBufferStringBuilder 1. String theorists are for the most part no longer actively pursuing connecting to particle physics of the real world. https://8ecm.si/prizes, Ashoke Sen has computed the logarithmic corrections to the Bekenstein-Hawking entropy of various standard black hole solutions in this paper. Everything is in the description. But this procedure you adopted in this post, is not the best way of understanding science, or communicating it. This is a joint work with Kwokwai Chan and Ziming Ma. I wonder how to find the number of ternary strings that have at least one 0, one 1 and one 2. Abstract: Three-dimensional N =4 supersymmetric field theories admit a natural class of chiral half-BPS boundary conditions that preserve N = (0, 4) supersymmetry. from 9:30 15:00 in So Paulo (8:30 14:00 in NY, 14:30 20:00 in Paris). We demonstrate the duality of quantum chaos quantities in the thermofield double state defined in a fermionic system. Estrada Dona Castorina 110, Jardim Botnico Properties of the construction are explained both purely in the context of holomorphic field theory and also by engineering the holomorphic theory on the worldvolume of a D-brane. He notes that to get at non-perturbative string theory we seem to need some more general understanding of quantum theories, going beyond the usual quantization starting with an action, and ends by saying maybe quantum information theory can help. 10. I believe that your permanent opposing the string hypes is good and welcomed. and finally I published a package on npm string-math. How do I check if an array includes a value in JavaScript? I will then summarise recent work (with Matthias Gaberdiel and others) on the AdS_3/CFT_2 correspondence, in the tensionless limit, which gives a proof of concept of the above ideas. It seems that non-stringy approaches to quantum gravity are not very successful at reproducing these universal results. This construction has several advantages and opens perspectives towards generalization to the case of the $cW$-algebras The plumbing graphs with matter can be viewed as certain kinds of quiver diagrams for 3d N=2 theories. In this talk, we will explain how to compute concrete equations of mirrors to blow-ups of toric varieties in the framework of the GrossSiebert program. Dear Peter, I believe you are cherry-picking parts of comments.

I agree with Felix. One can add superpotentials, which lead to Seiberg-like dualities between plumbing graphs with triangles. Title: Elliptic trace map on chiral algebras Abstract: Open quantum systems are of experimental interest since ideally real life experiments always have some interaction with its environment. AP Computer Science A. [Slides]. for Fundamental Research), [D] Juan Maldacena (Institute for Advanced Study), [T] Shiraz Minwalla (Tata Inst. David Morrison (University of California) The EMS prizes are always a good indication of future Fields medalists Since its online only, talks are much more accessible than usual (and since its free, over 2000 people have registered to in principle participate via Zoom). Nothing will be said about multiverses or swampland on what follows. Title: Holomorphic Floer theory and Donaldson-Thomas invariants Miranda Cheng But keep in mind that using the Function constructor in this way is similar to eval() in that the risks may be comparable. [Slides], Shi Cheng (University of Warsaw) Due to its interaction, the system density matrix and operators within the system Hilbert space evolve non-unitarily. This provides an enumerative interpretation of the A-model topological string partition function on non-commutative resolutions of the singular Calabi-Yaus. 3. A limit involving the quotient of two sums. 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. [Slides] [Video], Davide Gaiotto (Perimeter Institute) 1 Let n be a natural number, n3. How to check whether a string contains a substring in JavaScript? [Slides] [Video], Boris Pioline (Sorbonne Universit and CNRS) We also provide the action of braiding on the relevant branes, so we can calculate Khovanov homology for any knot given its braid representation. [Slides] [Video], Sam Raskin (University of Texas at Austin) Title: Giant Gravitons in Twisted Holography 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). We provide significant evidence that averaging plays an important role in reproducingsemiclassical gravity in AdS/BCFT. Title: Holographic tensor networks from hyperbolic buildings Organized by Mina Aganagic , Ivan Danilenko , Andrei Okounkov, and Peng Zhou. Physical Review, 85(4), p.631. Time permitting, we will discuss a number of related results, such as the cluster structures and Newton-Okounkov bodies determined for the exceptional family in [Spacek-Wang22], and connection to other mirror symmetry statements such as the quantum D-module isomorphism proven for minuscule homogeneous spaces in [Lam-Templier17].

Abstract: I will explain some recent and ongoing work on the state spaces associated to 3-manifolds in the Kapustin-Witten twists of 4d N=4 SYM. I just took a look at that session and thought one remarkable point was where people were asked what would cause you to give up on string theory? The only answers forthcoming were from Igor Klebanov, who said he had been working on it his whole life, so couldnt see himself giving up on it, and Ashoke Sen, who said he would only give up on it if it were shown to be mathematically inconsistent. Oh, God, how hard Ive slaved away, LHC will discover SUSY Abstract: Homological block, commonly denoted by , is a 3-manifold invariant whose existence was predicted by S. Gukov, D. Pei, P. Putrov, and C. Vafa in 2017 using 3d/3d correspondence. Paul-Konstantin Oehlmann (Uppsala University) Another talk of Penrose (and a conference in his honour): But this is just an opinion. Of course, a few minutes earlier Witten had explained that no one knows what the theory actually is, which means there is no way to show that it is mathematically inconsistent. 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. The operators satisfy an operator product expansion. http://silentmatt.com/javascript-expression-evaluator/, http://www.codeproject.com/KB/scripting/jsexpressioneval.aspx, I spent a couple of hours to implement all the arithmetical rules without using eval() and finally I published a package on npm string-math. Only if the string comes from a trusted source. Theres no reason to get into the technical argument over whether the perturbative expansion of various versions of the superstring in 10d is mathematically well-defined. Title: Non-Invertible Symmetries and Higher-Categories String-Math 2021 conference (IMPA, Rio de Janeiro), [R = Review lecture] ; [D = Discussion session] ; [T = Research talk] ; [P = Public lecture] ; [S = Starting/Summary talks] ; [G = Gong-show talk]. Title: Quivers for 3-manifolds We study an open quantum many body spin system to check whether its integrable and chaotic regimes can be distinguished by looking at the non-unitary dynamics of a simple operator in Krylov space. Recently, a rigorous probabilistic construction of the path integral was provided using the Gaussian Free Field. As you probably guess from my former comments under the present pseudonym, Im one of those students whom, maybe for lacking courage or ,who knows? Witten says something about a (possible) theory that is intrinsically quantum mechanical, which seems to mean a theory that does not start with a continuous field and quantise it, and which (therefore) presumably cannot be described in that way. 2013 Jul. I strongly disagree with you about the issue of the intellectual honesty of my account of what Witten and Arkani-Hamed had to say. If you want to be added to the seminar mailing list, use this link https . In particular, he discovered a hidden structure governed by Bernoulli numbers. People are attempting to understand things, with the tools at hand. This will be done in the language of QP manifolds/symplectic L-infinity algebroids which is convenient for showing the duality is a canonical transformation in string phase space, and also provides glimpses of a generalisation towards U-duality and higher branes. Abstract: The six-dimensional superconformal field theory associated to an ADE Lie algebra plays a key role in the AGT correspondence. So, does anyone know about alternatives to eval()? Mathematically, they can be identified with the K-theoretic versions of the Donaldson invariants on X. Philip Candelas From a mathematical perspective, these solutions involve interesting constructions in geometry such as integrable G2-structures and G2-instantons. 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. Please, watch the discussions (there were many) and appreciate that these were honest discussion. How to transform string into integers and operators in Javascript? The program is based on two main ingredients: The complex geometry of the underlying moduli spaces on the one hand, and cluster algebra structures defined by BPS- or DT-invariants on the other hand. [Slides], Kasia Budzik (Perimeter Institute) -) and postfix (e.g. Strings 2021 Summary Talk, So Paulo (June 21 - July 2, 2021) [on-line] . Breaking news: on July 5, 2022, Maryna Viazovska was awarded with the Fields medal, the highest recognition in mathematics! For different choices of superpotential, the LG theory categorifies the quantum knot invariants associated with any simply-laced Lie algebra. We therefore relate differential and enumerative geometry, topology and geometric representation theory in mathematics, via a maximally-supersymmetric topological quantum field theory with electric-magnetic duality in physics. I will also explain how the Hecke operators from geometric and analytic Langlands correspondence are realized in the four dimensional super-Yang-Mills theory. Chen-Te Ma (Asia Pacific Center for Theoretical Physics) This goes without saying all technically challenging fundamentally important problems required for superstring theory unification be at least mathematically self-consistent have been left unanswered. I will describe how to bootstrap these perturbative corrections without computing actual Feynman integralsand present some preliminary results for pure N=1 gauge theory. The general principle is that whenever you have a group acting on a physical quantum system, the state space will be a unitary representation of that group, and unitary representations break up into irreducible representations. In this tutorial, we'll discuss various approaches to evaluate a math expression using Java. Talks are available for watching every day via Youtube, links are on the main page. Black Hole Entropy and the Problem of Universality [https://arxiv.org/abs/gr-qc/0702094]. (With exception of a group of very few dedicated researches, to whom I sincerely keep my deep respects.) 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.

Title: A holomorphic approach to fivebranes If people think carrying on this argument is a good use of their time, they are encouraged to do so elsewhere. [Slides] [Video], Dalimil Mazac (IAS) Title: Finite symmetry in field theory We hereby certify that, Alex Buchel, THE UNIVERSITY OF WESTERN ONTARIO, Making statements based on opinion; back them up with references or personal experience. A ternary string is a sequence of n symbols that has some of the digits 0, 1, 2. String theory is now older than not just my students, but also many of their parents and unfortunately its very well-established, sometimes even taught to high school students. 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. Title: Integrability check for open quantum systems in Krylov Space Non-QG QFT derivations that are not attempting to identify the microstates. [Slides] [Video], Yaping Yang (University of Melbourne) !) Depending on the coupling constant and dimension, they exhibit several distinct scaling behaviors (or if you prefer the high energy jargon, various renormalization group flows). In the case of rank one instantons this factors through a `Heisenberg type super Lie algebra and the story is analogous to Nakajimas action on the Hilbert scheme. Dear Peter, [Slides], Muyang Liu (Uppsala University) Title: Quantum duality and Morita theory for chiral algebras [online talk] Just viewed the last question and answer session. In a different direction, I will in this talk present a conjectural picture relating holomorphic Floer theory of complex integrable systems to Donaldson-Thomas invariants. Are there any actual attempts in the literature to build such an intrinsically quantum theory, or is this just pie in the sky? Solutions to this system describe compactifications of heterotic string theory with N=1 supersymmetry on a 7-dimensional manifold. 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. Abstract: Gross and Siebert developed a program for understanding mirror symmetry algebro-geometrically. 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. Title: Spectrum in quantum mechanics and deformed periods [online talk] [Slides], Meng-Chwan Tan (National University of Singapore) 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. Maryna Viazovska was awarded with the Fields medal, https://www.fuw.edu.pl/faculty-of-physics-home.html, Hera guesthouse of the University of Warsaw (budget option), https://warsawgenomics.pl/en/sars-cov-2/koronawirus-rtpcr. for Fundamental Research), [T] Sebastian Mizera (Institute for Advanced Study), [T] Sameer Murthy (Kings College London), [S] Hirosi Ooguri (Caltech and Kavli IPMU), [D] Joo Penedones (cole Polytech.

[Slides] [Video], Edward Witten (IAS) [Slides] [Video], David Jordan (University of Edinburgh) This lecture is aimed for the general public and does not request much prerequisites in mathematics. To summarize the situation, now as it has ever been: 1. The recording of the lecture can be found here. We introduce a. new idea, boundary averaging, to address the question: Does averaging also work well in AdS/BCFT? To address this issue, we use the fusion-matrix bootstrap, which is recently developed in the context of the light-cone bootstrap. IMPA, Rio de Janeiro, June 14 18, 2021 Turned into an online eventSpeaker: Si Li (Tsinghua University)Lecture title: Elliptic chiral homology and quantum master equationEvent page: http://bit.ly/stringmath2021Videos playlist: https://bit.ly/3v2lHlsThe series of String-Math conferences has developed into a central event on the interface between mathematics and physics related to string theory, quantum field theory and neighboring subjects. I will present recent progress in this direction in the simplest case of local $P^2$, and argue that its global BPS spectrum and flow tree structure can be deduced from a scattering diagram with simple initial data. This is enabledby thesurprisingappearanceof a Penner-like matrix model whose spectral curve turns out to give a Strebel differential. Abstract: The problem of quantization of noncommutative spaces (spectral triples) is addressed first in a finite-dimensional, Euclidean setting (thus referred to as random noncommutative geometry, or Dirac ensambles). Starting from 1h14m of this meet the public vide Certain reformulations and consequences of cosmic censorship, however, may be true in asymptotically AdS solutions that admit a consistent holographic dual. In the presence of chiral multiplets that are added to plumbing graphs, we show that ST-transformations lead to many equivalent plumbing theories, and hence generalize the scope of Kirby moves. Abstract: Trace map on deformation quantized algebra leads to the algebraic index theorem. Biogram (in Polish): Maryna Viazovska urodzia si, uczya i studiowaa w Kijowie w Ukrainie. Nevertheless, from a theory claiming to be the only mathematically self-consistent unification program, something regarded as just a mere technicality now requires an answer. StringStringfinal . Elements of this Hilbert space can be thought of as local operators living in a (d-1)-dimensional spacetime. Physics Meets AI, LMU Munich, September 2020. Its explicit description as a QFT has remained elusive. There is also an open source implementation on GitHub, evaluator.js, and an NPM package. Condensed matter physics is a quite different story. Postal Address:Instituto de Matemtica Pura e Aplicada We propose that the matching of 5d coulomb branches plus the 2-group structure constants determined by the higher form symmetry of LSTs as criteria to predict heterotic T-dual candidates.The exploitation are generalized by picking non-trivial flat connections at the infinity to break E8 and Spin(32)/Z2 into their subgroups and confirm these T-dualities by the matching of criteria aforementioned. 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. [Slides], Nicolo Piazzalunga (Uppsala University) Of course even his brightest former student couldnt accept that: The experimental community pretty much politely ignores the string theory community, and has, well, since 1974 or so when the analytic S-matrix failed to predict the charmed quark. 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. In two dimensions, thesebounds allow us to determine the set of first eigenvalues attained by all hyperbolic orbifolds. Abstract: I will discuss the theory of Dirac operators perturbed by the Coulomb potential in an arbitrary dimension. Title: Families of solutions of the heterotic G2 system But I went through the hard road, being told just to accept all fundamental questions I raised above as unanswered and move on to the cutting-edge problems whatever and whonever decides what these are. Evaluator.js is a small, zero-dependency module for evaluating mathematical expressions. The original sphere packing problem in dimension 3 is known as Keplers conjecture and it was famously solved by Thomas Hales at the very end of the twentieth century.

Suomynona, His third talk emphasizes thinking of space-time vectors as two by two matrices (see section 40.4 of my QM book). 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. rev2023.3.3.43278. [Slides], Alex S. Arvanitakis (Vrije Universiteit Brussel) Title: Perturbative calculations in twisted 4d gauge theories [online talk] Dr. Kessner. The qubit example is a bit unfair since in some sense its the quantization of the sphere, although this sphere is not a classical limit of the quantum theory (and sphere isnt a cotangent bundle of some configuration space). The methods can also be extended to SU(n) or G2 structure metrics [Slides] [Video], Conan Leung (Chinese University of Hong Kong) To begin with, we'll discuss a few third-party libraries and their usage. with the exact opposite agenda. Invertible QFTs are expected to form a sheaf of \infty-groupoids, and we apply the framework of differential cohomology to this sheaf.
