Eigenforms of hyperelliptic curves with many automorphisms

Abstract
Given a pair of translation surfaces it is very difficult to determine whether they are supported on the same algebraic curve. In fact, there are very few examples of such pairs. In this note we present infinitely many examples of finite collections of translation surfaces supported on the same algebraic curve.
The underlying curves are hyperelliptic curves with many automorphisms. For each curve X, the automorphism group Aut(X) acts on the space of holomorphic 1-forms. We present a translation surface corresponding to each of the eigenforms of the automorphism of maximal order.

This research has emerged from a question of Curt McMullen on representations of eigenforms as translation surfaces. We also thank the anonymous referee whose comments helped to improve the exposition of the paper.
