Automorphisms of minimal entropy on supersingular K3 surfaces

Simon Brandhorst, Víctor González-Alonso

In this article we give a strategy to decide whether the logarithm of a given Salem number is realized as entropy of an automorphism of a supersingular K3 surface in positive chara…

Automorphisms of Salem degree 22 on supersingular K3 surfaces of higher Artin invariant

Simon Brandhorst

We give a short proof that every supersingular K3 surface (except possibly in characteristic $2$ with Artin invariant $σ = 10$ ) has an automorphism of Salem degree 22. In particular…

The classification of purely non-symplectic automorphisms of high order on K3 surfaces

Simon Brandhorst

An automorphism of order $n$ of a K3 surface is called purely non-symplectic if it multiplies the holomorphic symplectic form by a primitive $n$ -th root of unity. We give the class…
