On discrete versions of two Accola’s theorems about automorphism groups of Riemann surfaces

On discrete versions of two Accola’s theorems about automorphism groups of Riemann surfaces In this paper we give a few discrete versions of Robert Accola’s results on Riemann surfaces with automorphism groups admitting partitions. As a consequence, we establish a condition for $$\gamma $$ γ -hyperelliptic involution on a graph to be unique. Also we construct an infinite family of graphs with more than one $$\gamma $$ γ -hyperelliptic involution. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Analysis and Mathematical Physics Springer Journals

Abstract

In this paper we give a few discrete versions of Robert Accola’s results on Riemann surfaces with automorphism groups admitting partitions. As a consequence, we establish a condition for $$\gamma $$ γ -hyperelliptic involution on a graph to be unique. Also we construct an infinite family of graphs with more than one $$\gamma $$ γ -hyperelliptic involution.
