A family of surfaces with pg=q=2, \, K2=7 and Albanese map of degree 3

Abstract

We study a family of surfaces of general type with pg=q=2 and K2=7, originally constructed by Cancian and Frapporti by using the Computer Algebra System MAGMA. We provide an alternative, computer-free construction of these surfaces, that allows us to describe their Albanese map and their moduli space.
