Lecturer: Kęstutis Česnavičius (Université Paris-Saclay)

Abstract: The Grothendieck–Serre conjecture predicts that every generically trivial torsor under a reductive group scheme G over a regular local ring R is trivial. We will explain how to settle it in the case when G is quasi-split and R is unramified.
