Pluricanonical Geometry of Varieties Isogenous to a Product and Abelian Covers

Massimiliano Alessandro, Davide Frapporti, Christian Gleissner

We study canonical and pluricanonical maps of varieties isogenous to a product of curves, i.e., quotients of the form $X = (C_{1} \times \dots \times C_{n}) / G$ with $g (C_{i}) \geq 2$ and $…

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

Fabrizio Catanese, Davide Frapporti, Christian Gleissner +2

In this first part we describe the group $A u t_{Z} (S)$ of cohomologically trivial automorphisms of a properly elliptic surface (a minimal surface $S$ with Kodaira dimension…
