Cyclic Symmetry on Complex Tori and Bagnera-De Franchis Manifolds
Abstract
We describe the possible linear actions of a cyclic group G = Z /n on a complex torus, using the cyclotomic exact sequence for the group algebra Z [G]. The main application is devoted to a structure theorem for Bagnera-De Franchis Manifolds, but we also give an application to hypergeometric integrals.
