Singularities and vanishing cycles in number theory over function fields

Will Sawin

Published 2020-05-19Version 1

This article is an overview of the vanishing cycles method in number theory over function fields. We first explain how this works in detail in a toy example, and then give three examples which are relevant to current research. The focus will be a general explanation of which sorts of problems this method can be applied to.
