Jack Hall: Lefschetz theorems via localization

Time: Thu 2021-09-23 14.00 - 15.00

Location: Institut Mittag-Leffler, Seminar Hall Kuskvillan (alt. Zoom, meeting ID: 921 756 1880)

Participating: Jack Hall (University of Melbourne)

Abstract: I will discuss a new approach to Lefschetz style hyperplane theorems using localizations of triangulated categories. The approach is also applicable to the Fargues–Fontaine curve, an object of recent interest in arithmetic geometry.
