Introduction to the Bernstein-Sato polynomial in positive characteristic
[ 講演概要 ]
The Bernstein-Sato polynomial of a holomorphic function is an invariant that originated in complex analysis, and with now strong applications to birational geometry and singularity theory over the complex numbers. For example, it detects the log-canonical threshold as well as the eigenvalues of the monodromy action on nearby cycles. In this talk I will define a characteristic-p analogue of this invariant, I will survey some of its basic properties, and I will illustrate how its behavior reflects arithmetic phenomena. This will serve as an introduction to the talk by Hiroki Kato.
