On the cohomologically trivial automorphisms of elliptic surfaces I: $\chi (S)=0$

Fabrizio Catanese, Davide Frapporti, Christian Gleissner +2

In this first part we describe the group $Au{t}_{\mathbb{Z}}(S)$ of cohomologically trivial automorphisms of a properly elliptic surface (a minimal surface $S$ with Kodaira dimension…
