Generalized Kummer surfaces over finite fields

Algebraic Geometry 2026-04-10 v4

Abstract

In this paper, we prove a refinement of the Katsura theorem on finite group actions on abelian surfaces such that the quotient is birational to a K3K3 surface. As an application, we compute traces of Frobenius on the Neron--Severi groups of supersingular generalized Kummer surfaces over finite fields.
