Abstract: Open quantum systems are of experimental interest since ideally real life experiments always have some interaction with its environment. [Slides] [Video], Rajesh Gopakumar (ICTS, Bangalore) 2021-22. Certain reformulations and consequences of cosmic censorship, however, may be true in asymptotically AdS solutions that admit a consistent holographic dual. I will first sketch a broad approach to systematically understand the underpinnings of this still mysterious connection between gauge theories (in the large N limit) and perturbative closed string theory. See a live demo on the website. In the end, we also consider a two-qubit system to demonstrate that a different entanglement spectrum does not provide the same constraint to $hat{H}$. He mentions that one basic problem with this is that there is no understanding of what happens in time-dependent backgrounds, so, in particular, this is useless for addressing the big bang, which is the one place people now point to as a possible connection to real world data. That would be something like (a real implementation will be somewhat more complex, especially if you consider the use of parenthesis, but you get the idea). (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. The resulting quivers highlight fractionalization of those branes, that we determine for single and multiple brane stacks. 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. String Maths 2021 During the week of June 14-18 we will be hosting a major event in mathematical physics. Of course, these are people. Jacek Paweczyk Is it possible to create a concave light? CICADAS [i.e. 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. 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. Title: Emergence of Time from Unitary Equivalence 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. Since it's online only, talks are much more accessible than usual (and since it's free, over 2000 people have registered to in principle participate via Zoom). How is Jesus " " (Luke 1:32 NAS28) different from a prophet (, Luke 1:76 NAS28)? 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. The EMS prizes are always a good indication of future Fields medalists Thats about the general problem of quantizing a symplectic manifold, but my impression was that Witten was thinking of the even more general problem of a quantum theory with no known symplectic manifold of which it is the quantization. Davide Gaiotto StringStringBuilderStringBufferMath. There are slight differences regarding scoping, but they mostly behave the same, including exposure to much of the same security risks: You can't, at most you could do something retort like parsing the numbers and then separating the operations with a switch, and making them. In this talk I will present how these two threads of research can be combined and what comes as a reward. In this talk, we will discuss recent progress in constructing explicit examples of higher-categories describing non-invertible symmetries in quantum field theories of various spacetime dimensions ranging from d=3 to d=6. Ive personally never understood why showing that (unphysical limits of) your quantum theory gives the expected semi-classical result is anything other than a rather weak consistency check on your theory. Even beginning PhD students will no longer believe that ST is the only framework that reproduces BH entropy. Hello, Robert A. Wilson 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 . 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. Exactly because of this. Title: Counting BPS states with discrete charges in M-theory Starting from 1h14m of this meet the public vide Thank you. This is joint work with Constantin Teleman and Greg Moore. Title: The positive Grassmannian, amplituhedron, and cluster algebras [online talk] Ta strona wykorzystuje ciasteczka (cookies) w celu zapewnienia maksymalnej wygody w korzystaniu z naszego serwisu. I will then explain how to describe their representations using subcrystals and how they can be translated into the framings of the quivers. Everything is in the description. StringBufferStringBuilder 1. Title: q-series for so(3) and osp(1|2) Matilde Marcolli How to transform string into integers and operators in Javascript? Can I tell police to wait and call a lawyer when served with a search warrant? Skeptical challenging of arguments is supposed to be what science is all about, but the speakers in this panel made it seem that this is absolutely not something that is part of their field or what they do. I will argue that they are encoded in the topological string partition functions of the singular Calabi-Yau itself and its various non-commutative resolutions. Poor fool that I am, 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. LHC will discover SUSY Paul-Konstantin Oehlmann (Uppsala University) Abstract: Recently, higher categorical understandings of quantum field theories have been rapidly developing. The recording of the lecture can be found here. This is a joint work with K. Ohmori (U. Tokyo). Oh, God, how hard Ive slaved away, [Slides] [Video], Jan Dereziski (University of Warsaw) String-Math, June 2013. This talk is based on joint work with Si Li. [Slides] [Video], Mayuko Yamashita (Kyoto University) Participant responses to online questionnaire, Clickhereto use the Slack workspace of Strings 2021. Jednym z najwaniejszych osigni Maryny Viazovskiej jest rozwizanie tzw. Infinite Analysis 13 Autumn School on Quantum Dilogarithm, Modular Double, and Representation Theory. [Slides], Mateo Galdeano (University of Oxford) 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). I dont think I was misrepresenting those at all. 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. Non-QG QFT derivations that are not attempting to identify the microstates. Other than that, I'd use eval in this case. 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. Workshop on Categorification and geometric representation theory. I will also discuss a second application, a new definition of FJRW invariants in the presence of an arbitrary symmetry group. This is based on joint work with Raghavendran. 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. Philip Candelas In the discussion section, Vafa challenges him on this, saying he sees no indication that quantum information theory gives any insight into dualities he sees as the central aspect of the non-perturbative theory. Why are trials on "Law & Order" in the New York Supreme Court? [Slides], Shi Cheng (University of Warsaw) They are exactly solvable in terms of Whittaker functions. Juan Maldacena It's december of 2021, and the java world has been rattled by a log4j vulnerability. Please, no more about the only string theory can compute the Black Hole entropy arguments. Title: String integrability of defect CFT and dynamical reflection matrices In our examples we find agreement with the flux modularity conjecture of Kachru, Nally, and Yang. 4. There are other views, it is a matter of taste. Hirosi Ooguri (Caltech & IPMU) But in my view a real mistake in the long run. Particularly, the change of variable relating $SU(2)$ link invariants to the $SO(3)$ \& $OSP(1|2)$ link invariants plays a crucial role in explicitly writing the $q$-series. According to this philosophy, connection to particle physics appear[s] hopeless/parochial/unimportant. 3 years ago, F_K invariants of knot complements in 3-sphere have been proposed.

Title: Liouville conformal field theory: from the probabilistic construction to the bootstrap construction for Fundamental Research), [D] Juan Maldacena (Institute for Advanced Study), [T] Shiraz Minwalla (Tata Inst. 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. I will discussa phenomenon similar to Frobenius of modular representation theory. 10. Adrian, how sensitive is the procedure to choice of k_mu he did the case where k_mu included a boost). 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. I will present a general overview of the theory of CEIs, and discuss how it provides a conjectural approach to understanding enumerative mirror symmetry for the quintic threefold, in arbitrary genus. How do I connect these two faces together? I will discuss two such consequences the Penrose Inequality and constraints on the location of trapped surfaces as possible diagnostics for whether a given solution admits a consistent UV completion within AdS/CFT. Explicit $q$-series form for $\hat Z$ is known for $SU(2)$ group, supergroup $SU(2|1)$ and ortho-symplectic supergroup $OSP(2|2)$. Abstract: Currently, there is a strong interest in the study of non-invertible symmetries of quantum field theories. Clay Mathematics Institute, ContactEnhancement and Partnership ProgramMillennium Prize ProblemsPublicationsHome. where the dualisable dimensions are fibred over a `spectator base). Adrian, These boring predictions, if confirmed by DUNE, will show that also in experimental physics no real stuff is happening. Also I explain what is the dimension for a mathematician and why it is an extremely useful concept for everyone. [Slides] [Video], Mirjam Cvetic (University of Pennsylvania) Off topic, but the European congress of Mathematics has finished up. Still, I think the best choice you can make is to use eval, given that you're able to trust the source of the string. Abstract: I will describe a close analogy between the spectral geometry of hyperbolic manifolds and conformal field theory. Organized by Mina Aganagic , Ivan Danilenko , Andrei Okounkov, and Peng Zhou. 2014 June. 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. How do I replace all occurrences of a string in JavaScript? 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. Title: Smoothing, scattering and a conjecture of Fukaya [online talk] (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). This is a truly fundamental idea about space time geometry that gets too little attention in most physics courses. I hadn't known about this until your post. String Data 2020, CERN, December 2020. 1+ 2 *2' // 5 but ' 1 + +2* 2 ' // Error, This shows to be more performant than @vol7ron's solution. I believe that your permanent opposing the string hypes is good and welcomed. Francis (Skip) Fennell | Nov 3, 2021 . Jackiw-Teitelboim/PeterH, 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. Abstract: By studying M-theory on singular non-compact special holonomy spaces X we demonstrate, via a process of cutting and gluing of singularities that extend to the boundary of X, the appearance of 0-form, 1-form and 2-group symmetries in the resulting supersymmetric quantum field theory. with the exact opposite agenda. Abstract: About 40 years ago J. Zinn-Justin formulated several conjectures about the perturbative expansion of the spectrum a quantum Hamiltonian (for the polynomial potential in 1 variable). IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online eventSpeaker: Giovanni Felder (ETH Zrich)Lecture title: Superstring measure and the superper. He goes on to explain the landscape philosophy, which he sees string theorists (and himself) as now adopting. This public lecture is also a lecture in the Zapytaj fizyka series here is the lecture website. Title: Vafa-Witten Theory: Invariants, Floer Homologies, Higgs Bundles, a Geometric Langlands Correspondence, and Categorification [online talk] Title: Calculating Quantum Knot Homology from Homological Mirror Symmetry 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. Abstract: The D3-D5 and D2-D4 probe-brane systems with nonzero worldvolume flux are holographically dual to N=4 super Yang-Mills and ABJM theory in the presence of half-BPS domain walls. Exactly because of this. This is a joint work with Kwokwai Chan and Ziming Ma. Here's a quick basic example I came up with (updated (2011-06-26): cleaner w/ input boxes). The match can be extended to saddles which appear in non-trivial Coulomb branch vacua. 8. The simplest example is the qubit. His third talk emphasizes thinking of space-time vectors as two by two matrices (see section 40.4 of my QM book). I agree with Felix. [Slides], Aranya Bhattacharya (IISc, Bangalore) Additionally, Evaluator.js intelligently reports invalid syntax, such as a misused operator, missing operand, or mismatched parentheses. String Theory remains the most magical structure we have encountered in theoretical physics and the magic seems directly connected to the particle physics of the real world Finally, we will talk about the connections between the sphere packing problem and some mysteries of modern physics. Are there any actual attempts in the literature to build such an intrinsically quantum theory, or is this just pie in the sky? . Title: Algebras and Entropies 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. Dan Freed (University of Texas at Austin) Title: Heterotic little strings, T-duality and 2-group symmetries But I believe that in todays update of this post you were not intellectually honest. Robert A. Wilson, 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. To summarize the situation, now as it has ever been: 1. 1 Let n be a natural number, n3. Abstract: I will review the holomorphic twist of four-dimensional N=1 gauge theories and present the Feynman diagrams which control the perturbative corrections to the twistingsupercharge and to the higher operations available in the twisted theories. The only message I hear repeatedly is that String theory is the only game in town. 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. 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. We introduce a. new idea, boundary averaging, to address the question: Does averaging also work well in AdS/BCFT? commutative) spacetime case is well-known to yield the Yang-Mills(-Higgs) theory, namely almost-commutative manifolds, has to be replaced by its fuzzy counterpart already the classical level. ncdu: What's going on with this second size column? 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. In particular, i can not find a derivation of any black hole entropy from first principles in quantum gravity outside of string theory.
