Angelo Vistoli: An arithmetic valuative criterion for properness for tame stacks, and applications

Time: Thu 2021-10-14 14.00 - 15.00

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

Lecturer: Angelo Vistoli (Scuola Normale Superiore)

Abstract: I will report on joint work in progress with Giulio Bresciani. I will present a valuative criterion for properness for tame stacks (in the sense of Abramovich, Olsson and Vistoli); although the statement will be clear to the experts, some of its consequences seem to be new, and surprising.
