Actions on the Picard group of smooth Fano threefolds

Algebraic Geometry 2025-11-18 v1

Abstract

We classify the possible images of the action of the group of automorphisms of a smooth Fano threefold on its Picard group. We also study the first group cohomology of the Picard group for families of smooth Fano threefolds.
