Affine equivalence and saddle connection graphs of half-translation surfaces

Geometric Topology 2020-08-18 v3 Complex Variables

Abstract

To every half-translation surface, we associate a saddle connection graph, which is a subgraph of the arc graph. We prove that every isomorphism between two saddle connection graphs is induced by an affine homeomorphism between the underlying half-translation surfaces. We also investigate the automorphism group of the saddle connection graph, and the corresponding quotient graph.
