it is true that experiments are real physics. Title: Category of QFTs and differential cohomology Adrian Langer Cookies and PrivacyAboutEventsNews Yuya Kusuki (California Institute of Technology) (videos of the talks at the bottom). Za te oraz inne osignicia otrzymaa wiele prestiowych nagrd i wyrnie, m.in. 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. Unit 3 - String, Math | APCS My talk will be based on recent joint work with Baej Ruba. https://arxiv.org/pdf/0809.0305.pdf, Already at p.1 one reads, The Problem: According to textbooks, the passage from classical mechanics to quantum mechanics is made by replacing Poisson brackets with commutators. 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. [Slides], Kasia Budzik (Perimeter Institute) Title: Non-rational $widehat{su}(2)$ cosets and Liouville field theory StringStringBuilderStringBufferMath. Strings 2022 Summary Talk. David Morrison (University of California) What am I doing wrong here in the PlotLegends specification? This talk is based on joint work with Xenia de la Ossa, arXiv:2111.13221. 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. 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. The whole tone of the discussion was pretty depressing. Making statements based on opinion; back them up with references or personal experience. I do not know if outreach sessions like the ones we witnessed in this Strings-conference are the best idea. As Peter keeps on repeating, the denial of the string community to acknowledge the failure of string theory as a unification theory (which is nothing to be ashamed off: physics is full of beautiful theory that are not correct) is a shame for the physics community. Jim Halverson Leszek Hadasz (Jagiellonian University) [Slides], Aranya Bhattacharya (IISc, Bangalore) Not all N = (0, 4) boundary conditions admit such deformations. 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. Even beginning PhD students will no longer believe that ST is the only framework that reproduces BH entropy. It's december of 2021, and the java world has been rattled by a log4j vulnerability. 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. I will discussa phenomenon similar to Frobenius of modular representation theory. While the community just spread out to other problems. It is expected that the right mathematical structure to capture physical properties of such symmetries is that of higher-categories.

Any other way wouldn't be as efficient. 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. Title: Towards F-theory MSSMs In my talk, I will discuss the following two examples. 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. Equivalent plumbing graphs suggest dual theories. Hawking tells you what the semiclassical limit is. It will often be a good idea to analyze states in terms of these irreducible representations. Dear Peter, I believe you are cherry-picking parts of comments. Zygmunt Lalak 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. Matthias Gaberdiel Extending this story, I will talk about other physical realizations of analytically continued systems, such as Regge poles, replicas, or dimensional regularization. Interestingly, most of the structures uncovered have a fractal boundary at infinity, which possesses a rich geometric structure. Sorry, but deleted various attempts to carry on the experimentalist vs. theorist mudfight of Ellis_AND_Wooster/Andr. Recently, a rigorous probabilistic construction of the path integral was provided using the Gaussian Free Field. Finally, I will discuss some applications. For different choices of superpotential, the LG theory categorifies the quantum knot invariants associated with any simply-laced Lie algebra. Mathematically, they can be identified with the K-theoretic versions of the Donaldson invariants on X. Title: Counting BPS states with discrete charges in M-theory Title: Dirac-Coulomb Hamiltonians[online talk] The EMS prizes are always a good indication of future Fields medalists All major operations, constants, and methods are supported. Im no whit wiser than when I began. 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. So I wrote that list as both an act of rebellion nevertheless also of relive: I dont think one needs to wait for Plancks law to clean up our field through funerals in this century anymore & heres the right point for me to close: Its time for new ideas and we are going to find them. Title: Magnetic quivers for Superconformal Field Theories Title: Non-Invertible Symmetries and Higher-Categories I will then explain how to describe their representations using subcrystals and how they can be translated into the framings of the quivers. 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. 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. NN-QFT Correspondence. [Slides] [Video], Antoine Bourget (CEA Saclay) String Math 2021 - Lara Anderson (Virginia Tech) - YouTube 2013 Jul. Title: Smoothing, scattering and a conjecture of Fukaya [online talk] Additionally, Evaluator.js intelligently reports invalid syntax, such as a misused operator, missing operand, or mismatched parentheses. [Slides], Shi Cheng (University of Warsaw) This relation originally developed from the point of view of matrix models, was later studied from the point of view of conformal field theory. The next String Math conference will take place on July 10-14, 2023, at the University of Melbourne in Australia. In this talk I will introduce the heterotic G2 system and show how to construct families of solutions using homogeneous 3-Sasakian manifolds with squashed metrics. Abstract: The sphere packing problem is a very natural geometric question and it has a long and exciting history. (iii) Most superstring calculations are performed under euclidean worldsheet for many practical reasons, as we all know and love from Wicks rotation in standard q.f.t.s. Suomynona, Infinite Analysis 13 Autumn School on Quantum Dilogarithm, Modular Double, and Representation Theory. 4. The proof in these cases uses the notion of 1-form symmetries (= co-dimension 2 topological defects) to express PGL(N)-skein modules as certain twisted SL(N)-skein-modules, and then to further relate these to well-known formulas for the cohomology of twisted character varietiesof surfaces. with the exact opposite agenda. This community is indeed becoming like a religious cult, something one of the speakers explicitly denied. Over-claim?

Wilson, Title: Approximations for Calabi-Yau and other special holonomy/structure metrics Of course there are many ways to obtain the BH formula that do not try to identify the microscopic degrees of freedom in a theory of QG, the original calculation from the 70s being an obvious example. Can they make mistakes? 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. Are there any actual attempts in the literature to build such an intrinsically quantum theory, or is this just pie in the sky? 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. 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. There are many equivalent graphs that are related by Kirby moves which are interpreted as integrating out gauge nodes from the perspectives of 3d theories. Strings 2021 Summary Talk, So Paulo (June 21 - July 2, 2021) [on-line] . 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]. String theorists are for the most part no longer actively pursuing connecting to particle physics of the real world. But this is just an opinion. Title: Geometry of Higher-Form Group Structures in String Theory 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. Abstract: The main goal of this talk is to present a novel conjectural incarnation of Langlands duality in the purely topological setting of character varieties of 3-manifolds and their quantizations via skein theory. The resulting quivers highlight fractionalization of those branes, that we determine for single and multiple brane stacks. This topic has been recently explored,from several differentperspectives,by Kontsevich-Soibelman and Doan-Rezchikov. Title: Path integral derivations of K-theoretic Donaldson invariants rotations and translations are typically discretized due to the presence of a lattice)? Paraphrasing Fermat, I have discovered the ugly truth of this, which this margin is too narrow to contain. Nevertheless, it may be worthy registering on this blog some of those problems which arent enough emphasized. !) What hes doing is emphasizing ideas that are often not taught in conventional QFT courses (although they should be). (not not) operator in JavaScript? Abstract: Three-dimensional N =4 supersymmetric field theories admit a natural class of chiral half-BPS boundary conditions that preserve N = (0, 4) supersymmetry. [Slides], Thorsten Schimannek (LPTHE Paris) 3 years ago, F_K invariants of knot complements in 3-sphere have been proposed. crickets]. I will also explain how the Hecke operators from geometric and analytic Langlands correspondence are realized in the four dimensional super-Yang-Mills theory. Explicit $q$-series form for $\hat Z$ is known for $SU(2)$ group, supergroup $SU(2|1)$ and ortho-symplectic supergroup $OSP(2|2)$. Of course, these are people. 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. According to this philosophy, connection to particle physics appear[s] hopeless/parochial/unimportant. and finally I published a package on npm string-math. Enjoy, This solution also clips whitespaces and checks for duplicating operators, e.g. ' I just had a look at that session, and more than anything, felt sorry seeing such eminent physicists giving such vacuous reasons just for the sake of defending a theory they have worked on for a long time. String Theory Explained: A Basic Guide to String Theory https://www.youtube.com/watch?v=WwmxaXTnGMI If youre so concerned about the public or physics community getting misled, surely youve contacted the organizers of and participants in the conferences Outreach activities , To this I was referring with my phrase A better version was given September 22, 2021 at Yan Soibelman's M-seminar.

How would you please implement. Abstract: Liouville field theory was introduced by Polyakov in the eighties in the context of string theory. I believe I am not misguided. If you cannot make it work with a default operator, I suggest you ask a new question, pointing out where exactly you get stuck.

Title: The higher dimensional tropical vertex Title: Heterotic little strings, T-duality and 2-group symmetries Piotr Sukowski (chair) Abstract: One aspect of the relation between physics and arithmetic geometry is the conjectured correspondence between supersymmetric flux vacua and weight-2 modular CY threefolds. IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online eventSpeaker: Alba Grassi (CERN)Lecture title: Painlev equations, quantum operators and gaug. In our examples we find agreement with the flux modularity conjecture of Kachru, Nally, and Yang.

As a part of Jhan Dhan Yojana, Bank of Baroda has decided to open more number of BCs and some Next-Gen-BCs who will rendering some additional Banking services. We as CBC are taking active part in implementation of this initiative of Bank particularly in the states of West Bengal, UP,Rajasthan,Orissa etc.
We got our robust technical support team. Members of this team are well experienced and knowledgeable. In addition we conduct virtual meetings with our BCs to update the development in the banking and the new initiatives taken by Bank and convey desires and expectation of Banks from BCs. In these meetings Officials from the Regional Offices of Bank of Baroda also take part. These are very effective during recent lock down period due to COVID 19.
Information and Communication Technology (ICT) is one of the Models used by Bank of Baroda for implementation of Financial Inclusion. ICT based models are (i) POS, (ii) Kiosk. POS is based on Application Service Provider (ASP) model with smart cards based technology for financial inclusion under the model, BCs are appointed by banks and CBCs These BCs are provided with point-of-service(POS) devices, using which they carry out transaction for the smart card holders at their doorsteps. The customers can operate their account using their smart cards through biometric authentication. In this system all transactions processed by the BC are online real time basis in core banking of bank. PoS devices deployed in the field are capable to process the transaction on the basis of Smart Card, Account number (card less), Aadhar number (AEPS) transactions.
