Polynomial Invariants of the Heisenberg Group with extra Symmetries

Alessandra Sarti

Let denote a finite subgroup containing the Heisenberg group. In these notes we classify all these groups, we find the dimension of the spaces of -invariant pol…

Polyhedral Groups and Pencils of K3-Surfaces with Maximal Picard Number

Wolf Barth, Alessandra Sarti

A K3-surface is a (smooth) surface which is simply connected and has trivial canonical bundle. In these notes we investigate three particular pencils of K3-surfaces with maximal Pi…
