Title:
Algebraic versus topological entropy for surfaces over finite fields
Time & Venue:
2019.11.20 17:00-18:00 C110
Abstract:
For an automorphism of an algebraic variety, we consider some properties of eigenvalues of the induced linear transformation on l-adic cohomology, motivated by some results from complex dynamics, related to the notion of entropy. This is a report on joint work with Hélène Esnault, and some subsequent work of K. Shuddhodan.
