Geometry and Topology Seminar - Gabriel Islamboul - Stable equivalence of smooth 4-manifolds described as sequences of handlebodies

Description

Speaker: Gabriel Islamboul (University of California Davis)

Title: Stable equivalence of smooth 4-manifolds described as sequences of handlebodies

Abstract: Following constructions of numerous authors, one can build a smooth 4-manifold from a loop of Morse functions on a surface, a loop in the cut complex, a loop in the pants complex, or from a multisection diagram. In this talk, we will discuss these constructions, as well as outline a stable equivalence theorem for these descriptions so that, for example, any two loops of Morse functions on a surface corresponding to the same smooth 4-manifold are related by a sequence of given operations.
