Title |
Frobenius Arithmetic for Frobenius Geometry |
Abstract |
There is a close relationship between the geometry of a variety in characteristic p and the action of Frobenius on its cohomology. This raises the question of how that action varies in a family of varieties of varying characteristic. I will describe our state of knowledge about the distribution of Frobenius conjugacy classes from this geometric perspective. My new results compute the exact density of a certain type of Frobenius action for varieties where we previously only knew lower bounds. |
