Europe/Rome Professor Gukov obtained his PhD in 2001 from Princeton University under the supervision of Edward Witten. He then was a Long-term Prize Fellow of Clay Mathematics Institute at Harvard University and then a member at the School of Mathematics at the Institute of Advanced Study in Princeton. Since 2007 he has been a professor of theoretical physics and mathematics at California Institute of Technology. From 2010 he has been also an external scientific member at Max Planck Institute for Mathematics in Bonn. Professor Gukov has made numerous significant contributions in string theory, quantum field theory and low dimensional topology. Abstract. Quantum physics, topology, and representation theory have a long history of working together. Therefore, it is no surprise that symmetries and their representations play an important role in describing physical phenomena and often label powerful invariants of 3-manifolds and 4-manifolds. More surprising, though, are algebraic structures labeled by topological manifolds or emergence of symmetries in quantum systems where they are not initially expected. Although instances of such 'hidden' algebraic structures are still rare and quite mysterious, they sometimes can be understood or even predicted in the framework of string theory. In this talk, intended for a broad audience, I will survey some of the recent and more intriguing examples of such relations between algebra, topology, and physics.

ICTP HECAP & Maths Colloquium on "Hidden Algebraic Structures in Topology and Quantum Field Theory"

Speaker(s): Sergei Gukov (California Institute of Technology, USA)

Colloquium Start Time: 17:00

Europe/Rome Stéphane Mallat is an applied mathematician, Professor at the Collège de France on the chair of Data Sciences. He is a member of the French Academy of Sciences, the Academy of Technologies and a Foreign Member of the US National Academy of Engineering. He was Professor at the Courant Institute of NYU in New York for 10 years, then at Ecole Polytechnique and Ecole Normale Supérieure in Paris. He also was the co-founder and CEO of a semiconductor start-up company. Stéphane Mallat's research interests include machine learning, signal processing and harmonic analysis. He developed the multiresolution wavelet theory with applications to image processing and sparse representations. He now works on mathematical understanding of deep neural networks, and their applications. ABSTRACT: Deep neural networks obtain impressive results for image, sound and language recognition or to address complex problems in physics. They are partly responsible of the renewal of artificial intelligence. Yet, we do not understand why they can work so well and why they fail sometimes, which raises many problems of robustness and explainability. Recognizing or classifying data amounts to approximate phenomena which depend on a very large number of variables. The combinatorial explosion of possibilities makes it potentially impossible to solve. One can learn from data only if the problem is highly structured. Deep neural networks appear to take advantage of these unknown structures. Understanding this "architecture of complexity" involves many branches of mathematics and is related to open questions in physics. I will discuss some approaches and show applications.
