Smooth k-double covers of the plane of geometric genus 3
Federico Fallucca, Roberto Pignatelli

Abstract. Abstract. In this work we classify all smooth surfaces with geometric genus equal to three and an action of a group G isomorphic to (Z/2)k such that the quotient is a plane. We find 11 families. We compute the canonical map of all of them, finding in particular a family of surfaces with canonical map of degree 16 that we could not find in the literature. We discuss the quotients by all subgroups of G finding several K3 surfaces with symplectic involutions. In particular we show that six families are families of triple K3 burgers in the sense of Laterveer.
