October 18, 2022 9:00 amI will present a review about recent progress in chartin non-invertible symmetries for four-dimensional quantum field theorie that have a six-dimensional origin. These include in particular N= supersymmetric Yang-Mills theories, and also a...

October 18, 2022 3:00 pmI will explain how to reinterpret invariant distributions on p-adic GL_n and its Lie algebra using symmetric functions. This reinterpretation, combined with some old results of Waldspurger, allows us to...

Gauge Theory and Topology Seminar, SEMINARS
October 14, 2022 3:30 pmRepresentations of 3-manifold groups into groups such as SU(2) and SL(2,C) have been actively studied for decades. Many topological invariants are defined by considering these representations, such as the Casson...

October 14, 2022 11:00 amSolutions of the algebraic Bethe ansatz for quantum magnet chains are, generally, multivalued functions of the parameters of the integrable system. I will explain how to compute some monodromies of solutions...

ALGEBRAIC DYNAMICS, SEMINARS
October 13, 2022 4:00 pm I will discuss joint work with V. Alexeev which builds a correspondence between degenerations of polarized K3 surfaces and integral-affine structures on the 2-sphere containing a weighted balanced graph. Under...
