| 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. |
