Title:On the constancy regions for mixed test ideals
Seminar:Algebra and Number Theory Seminar
Speaker:Felipe Perez, University of Michigan
Abstract:
Given a regular ring R of characteristic zero and an elements  f_1,...,f_r in R the  mixed multiplier ideal encodes information about the singularities of mixed products of the f_i. In characteristic zero the constancy regions for mixed multiplier ideals consist of rational polytopes with non-overlapping interiors. In positive characteristic, the test ideals are the analogue of multiplier ideals. In this talk we study the situation for mixed test ideals and describe the constancy regions as p-fractals.
