Title: Self maps of varieties over finite fields.

Abstract: Esnault and Srinivas proved that as in de Rham cohomology over
the complex numbers, the value of the entropy of an automorphism of a
smooth proper surface over a finite field $\F_q$ is taken in the span of
the Neron-Severi group inside of of $\ell$-adic cohomology. In this talk
we will discuss some analogous questions in higher dimensions motivated by
their results and techniques.
