Toroidal b-divisors and Monge-Ampère measures

May 13 at 15:0016:00 CEST

TGiZ-Seminar: Tropical geometry in Zoom (First meeting Summer Semester 2022)

Ana María Botero (Regensburg University)

Abstract:
A b-divisor on a smooth projective algebraic variety X is an element in the projective limit of divisors, indexed over all smooth proper modifications of X, and satisfying some functoriality properties. Amongst all b-divisors, the so-called “toroidal” ones can be studied using convex-geometrical and tropical techniques. The aim of the talk is to give an overview of the theory. This joint work with Jose Burgos and Martin Sombra.
