Jacobians with with automorphisms of prime order (2109.06794v3)
Published 14 Sep 2021 in math.AG, math.CV, and math.NT
Abstract: In this paper we study principally polarized abelian varieties that admit an automorphism of prime order $p>2$. It turns out that certain natural conditions on the multiplicities of its action on the differentials of the first kind do guarantee that those polarized varieties are not jacobians of curves.
