Abstract

The F-pure threshold is a positive characteristic invariant of singularities, and can be thought of as an analog of the log canonical threshold in characteristic zero. These two invariants have numerous properties in common, although showing them generally requires involves different methods. In this talk, I will describe recent work with K. Schwede showing the rationality of the F-pure thresholds of ideals in power series rings.
