Abstract

Ishizaka classified up to conjugacy hyperelliptic periodic automorphisms of a surface. Here, an involution II on a surface Σg\Sigma_{g} is hyperelliptic if and only if Σg/I\Sigma_{g}/\langle I \rangle is homeomorphic to S2S^2. In this article, we give a classification up to conjugacy for irreducible periodic automorphisms of a surface Σg\Sigma_{g} which commute with involutions ι\iota such that Σg/ι\Sigma_{g}/\langle \iota \rangle is homeomorphic to T2T^{2}.
