Title:F-pure thresholds vs. log canonical thresholds
Seminar:Algebra and Number Theory Seminar
Speaker:Shunsuke Takagi, MIT and Kyushu University
Abstract:
The log canonical threshold is an invariant of singularities in characteristic zero defined via resolutions of singularities. It plays an important role in higher-dimensional birational geometry. On the other hand, the F-pure threshold is an invariant of singularities in positive characteristic defined via the action of the Frobenius morphism. In this talk, I will discuss a comparison of these two invariants.
