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. fiendish mathematics and mind-boggling . Title: On topology change in Poisson-Lie T-duality The problem with the string theory hype is not that its new, exciting, cutting-edge speculation, rather than well-established. Finally, I will mention how some of these features are likely to persist in a proposal for the worldsheet dual of free N=4 Super Yang-Mills theory. Goodbye eval()! @David Roberts: There are many references that discuss this from different perspectives. from 9:30 15:00 in So Paulo (8:30 14:00 in NY, 14:30 20:00 in Paris). 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: The heterotic G2 system is the 7-dimensional analogue of the Hull-Strominger system. Notes (with animations), Video. Abstract: Holomorphic Floer theory is the analogof Floer theoryfor holomorphic symplectic manifolds. String Math 2021 IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online event The 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. NN-QFT Correspondence. 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. Davide Gaiotto Nov 22-26, 2021: Higher structures in geometry and physics, Chern Institute of Mathematics, Nankai University 9. Dear Peter, I believe you are cherry-picking parts of comments. 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. My talk will be based on recent joint work with Baej Ruba. Strings 2021 started today, program is available here. How do I check if an array includes a value in JavaScript? 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. You wrote Solutions to this system describe compactifications of heterotic string theory with N=1 supersymmetry on a 7-dimensional manifold. Any consistent theory of quantum gravity should reproduce this semiclassical limit. 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). How do I align things in the following tabular environment? Moving away from such orbifold points requires generalizing the flow tree formula from the Abelian category of quiver representations to the derived category of the same. 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. 4. Interestingly, most of the structures uncovered have a fractal boundary at infinity, which possesses a rich geometric structure. 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: How can I find out which sectors are used by files on NTFS? Title: Path integral derivations of K-theoretic Donaldson invariants All major operations, constants, and methods are supported. where the dualisable dimensions are fibred over a `spectator base). Another talk of Penrose (and a conference in his honour): Condensed matter physics is a quite different story. 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]. Extending this story, I will talk about other physical realizations of analytically continued systems, such as Regge poles, replicas, or dimensional regularization. The LQG example hardly qualifies if you do not have any way to fix the Immirzi parameter and just tune it to get the desired result. LHC will discover SUSY It fully encodes the geometry, and a simple algorithm allows access to the structure of nested singularities, which corresponds physically to a generalized Higgs mechanism. How to transform string into integers and operators in Javascript? One can add superpotentials, which lead to Seiberg-like dualities between plumbing graphs with triangles. In this talk, I will explain how to prove their conjecture for a big class of link complements by making use of the R-matrix for Verma modules. 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. [Slides]. This provides an enumerative interpretation of the A-model topological string partition function on non-commutative resolutions of the singular Calabi-Yaus. Mathematically, they can be identified with the K-theoretic versions of the Donaldson invariants on X. String Theory Loves SUSY + Unification, to what they are saying now that the LHC has found no SUSY. Philip Candelas Once again, this is just an opinion. Title: Deriving Gauge-String Duality Even without LQG, there are many ideas on/in QG which are physically well founded. But in my view a real mistake in the long run. Paul-Konstantin Oehlmann (Uppsala University) String-Math, June 2013. https://sites.google.com/unifi.it/scri21/program Title: BPSDendroscopyon local Calabi-Yau threefolds Note : There is no library used in this solution purely hard coded, My solution takes into account of brackets also like 8+6(7(-1)) or 8+6(7(-1)), You can do these operations ^, *, /, +, -, To calculate a string use calculate(tokenize(pieval("8+6(7(-1))").join(""))). Miosz Panfil I am not a fan of string theory. 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. Lakshya Bhardwaj (University of Oxford) 2. String-Math 2015, Hainan Island, China (December 31, 2015 - January 4, 2016; How to Quantize Gravity. Abstract: In this talk, I will revisit the construction of heterotic ALE instantons and the corresponding T-dual systems in 6D little string theories (LSTs). Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. (With exception of a group of very few dedicated researches, to whom I sincerely keep my deep respects.) Enjoy. [Slides], Pawe Ciosmak (IDEAS NCBiR) An exchange that was otherwise quite lively and interesting, you paint in the worst possible way. [Slides]. [Slides], Muyang Liu (Uppsala University) Odbya stae podoktorskie na uniwersytecie Humboldta w Berlinie oraz uniwersytecie w Princeton w USA, a nastpnie zostaa profesorem w cole Polytechnique Fdrale de Lausanne (EPFL) w Szwajcarii, gdzie od 2018 roku kieruje Katedr Teorii Liczb. But this procedure you adopted in this post, is not the best way of understanding science, or communicating it. Abstract: I will explain how to explicitly calculate knot homology using the Fukaya category associated to a 2d Landau-Ginsburg theory, which is the equivariant mirror of the Coulomb branch of a 3d $mathcal{N}=4$ theory. The linking numbers of plumbing graphs are interpreted as the effective mixed Chern-Simons levels of 3d N=2 theories with chiral multiplets. 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. Check this JSBenchmark. And how I regret it, D-branes also 10. Abstract: Liouville field theory was introduced by Polyakov in the eighties in the context of string theory. The simplest example is the qubit. T-duality then becomes a fibre-base duality of the threefold which allows us to compute the little-string-charges directly from the Kac labels of the dual gauge groups. . Abstract: In this talk I will introduce a refined notion of Gopakumar-Vafa invariants on singular Calabi-Yau threefolds that generate a discrete gauge symmetry in M-theory. It seems that no one in the string theory community dares to publicly breathe a word of skepticism. 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. We focus on $\hat Z$ for $SO(3)$ group and orthosymplectic supergroup $OSP(1|2)$. String theorists are for the most part no longer actively pursuing connecting to particle physics of the real world. String Math 2021, held online by IMPA, Rio de Janeiro, Rio de Janeiro, June 14 - 18, 2021. How to evaluate string mathematical expressions in java script? Dec 18, 2021 at 16:43. 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. We construct a trace map on the elliptic chiral homology of the free beta gamma-bc system using the BV quantization framework. How to check whether a string contains a substring in JavaScript? How is Jesus " " (Luke 1:32 NAS28) different from a prophet (, Luke 1:76 NAS28)? Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2, Evaluate an Equation in Javascript, without eval(), Stand-in mathematical replacement for eval. 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: 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. +1 upvote from me, and I've already used it in a project. Title: Finite symmetry in field theory Mina Aganagic Braces are not supported, am I right? 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). We introduce a new idea, boundary averaging, to address the question: Does averaging also work well in AdS/BCFT? On the utility of the equation 2+4=6 in supersymmetric quantum field theory. [Slides], Sam Gunningham (Montana State University) CICADAS [i.e. David Ben-Zwi Title: Topological Langlands duality and 1-form symmetries We demonstrate the duality of quantum chaos quantities in the thermofield double state defined in a fermionic system. 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). Title: Quantum duality and Morita theory for chiral algebras [online talk] 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. We will focus on understanding 3d mirror symmetry viachiralalgebras. Greg Moore To summarize the situation, now as it has ever been: 1. 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. Maxim Kontsevich (IHS) 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. Title: Quantum curves and vertex algebras Experimentalist: I have to compute QCD, Wikipedia says I need to add unphysical ghosts on a local section and their fiberwise duals and project out the quotient Fock space isomorphic to the supergraded BRST cohomology pullback of the field configuration along a vertical diffeomorphism of the principal BatalinVilkovisky anafestic G-bundle, as if it were antani. Yes, I was ignoring some other things they had to say, for example, Arkani-Hameds 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. 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. A hyperbolic d-manifold gives rise to a Hilbert space which is a unitary representation of the conformal group in d-1 dimensions. 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. That looks nothing like the real world, and as Minwalla points out, no one at the Strings conference is even talking about that sort of string theory anymore. If people think carrying on this argument is a good use of their time, they are encouraged to do so elsewhere. A ternary string is a sequence of n symbols that has some of the digits 0, 1, 2. This is exactly the place where you should be using eval(), or you will have to loop through the string and generate the numbers. 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. In two dimensions, thesebounds allow us to determine the set of first eigenvalues attained by all hyperbolic orbifolds.

Title: Holomorphic Floer theory and Donaldson-Thomas invariants 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. Do I need a thermal expansion tank if I already have a pressure tank? This talk is based on joint work with Xenia de la Ossa, arXiv:2111.13221. 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. How do I make the first letter of a string uppercase in JavaScript? 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).
