Topology Seminar: Alex Sherman (University of New South Wales)
Title: Semisimplifying categorical Heisenberg actions, diagrammatics, and periodic equivalences Abstract: Semisimplification functors on tensor categories underlie many powerful constructions in representation theory, including the Frobenius functor in modular representation theory and the Duflo-Serganova functor from Lie superalgebras. I will introduce a systematic approach to applying semisimplification functors to categories defined over positive characteristic, with the most […]

Title:Self-similar singularities in fluids and related equationsAbstract:In this talk, we will present recent developments in constructing self-similar singularities in the compressible Euler equations and the nonlinear wave equation, associated with implosion. Our approach combines ODE techniques, weighted energy estimates, compact perturbation methods, and soft functional analysis arguments.
