Grothendieck ring of varieties and birational geometry

Semester
SoSe 2024

Lecturer
Pavel Sechin

Type of course (Veranstaltungsart)
Oberseminar

German title
Der Grothendieck Ring der algebraischen Varietäten

Contents
The goal of this seminar is to study some of the recent advances of applications of the Grothendieck ring of varieties to the questions of birational geometry.

In particular, we will address the properties of specialization of stable birationality and rationality in families with 'mild' singularities.
