Title: On semi-continuity problems for minimal log discrepancies

Date: Tue, Apr 02, 2013, 13:15 - 14:45

Place: Seminar Room A

Abstract: The conjecture of termination of flips is still an open
problem in the theory of minimal model program. There are two related
conjectures about minimal log discrepancies, LSC (lower
semi-continuity) conjecture and Musta＼c{t}＼u{a}'s conjecture. We show
LSC conjecture for varieties which have a crepant resolution in the
category of Deligne-Mumford stacks. Using this property, we also prove
Musta＼c{t}＼u{a}'s for toric triples.
