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 with and $…
Cohomologically or numerically trivial automorphisms of surfaces of general type
Fabrizio Catanese, Davide Frapporti
Our main result is the determination of the respective groups of cohomologically trivial automorphisms and of numerically trivial automo…
Varieties of Nodal surfaces, coding theory and Discriminants of cubic hypersurfaces. Part 1: Generalities and nodal K3 surfaces. Part 2: Cubic Hypersurfaces, associated discriminants. Part 3: Nodal quintics. Part 4: Nodal sextics
Fabrizio Catanese, in collaboration with Yonghwa Cho, Stephen Coughlan +4
We attach two binary codes to a projective nodal surface (the strict code K and, for even degree d, the extended code K' ) to investigate the `Nodal Severi varieties F(d, n) of nod…
On the cohomologically trivial automorphisms of elliptic surfaces I:
Fabrizio Catanese, Davide Frapporti, Christian Gleissner +2
In this first part we describe the group of cohomologically trivial automorphisms of a properly elliptic surface (a minimal surface with Kodaira dimension…
