Abstract

The Bers–Greenberg theorem tells us that the Teichmüller space of a Riemann surface with branch points (orbifold) depends only on the genus and the number of special points, and not on the particular ramification values. On the other hand, the Maskit embedding provides a mapping from the Teichmüller space of an orbifold, into the product of one-dimensional Teichmüller spaces. In this paper we prove that there is a set of isomorphisms between one-dimensional Teichmüller spaces that, when restricted to the image of the Teichmüller space of an orbifold under the Maskit embedding, provides the Bers–Greenberg isomorphism.
