Singular Support for Constructible Sheaves in Étale Topology

Explore a mathematical seminar talk where Alexander Beilinson delves into the concept of singular support for constructible sheaves, tracing its evolution from analytical origins in wave front distributions to its applications in D-module theory. Learn about Kashiwara and Shapira's development of constructible sheaves in classical topology during the 1980s, and discover how these concepts extend to étale versions relevant to restricted geometric Langlands theory. Gain insights into this advanced mathematical topic through a comprehensive two-hour presentation that bridges multiple mathematical disciplines and theoretical frameworks.
