Algebraic versus topological entropy for surfaces over finite fields
Esnault, Hélène · Srinivas, Vasudevan
Original · EN
We show that, as in de Rham cohomology over the complex numbers, the value of the entropy of an automorphism of the surface over a finite field is taken on the span of the Néron-Severi group inside of ℓ-adic cohomology. v2: (some) typos removed, exposition (partly) improved.
