Title:F-pure thresholds of quasi-homogeneous polynomials
Seminar:Algebra and Number Theory Seminar
Speaker:Daniel Hernandez, University of Minnesota
Abstract:
The F-pure threshold of a polynomial over a finite field is a numerical invariant which measures the singularities of the associated hypersurface. Amazingly, this prime characteristic invariant is closely related to the log canonical threshold, a well-known invariant of singularities in characteristic zero. In this talk, we recall the relationship between these two invariants, and will present recent work regarding the computation of F-pure thresholds for quasi-homogeneous polynomials. This is joint work with Luis Nunez Betancourt, Emily Witt, and Wenliang Zhang. Note that some of our methods are based on ideas of Bhargav Bhatt and Anurag Singh.
