A Short Note On M-Symmetric Hyperelliptic Riemann Surfaces

open access: yesCubo, 2010
We provide an argument, based on Schottky groups, of a result due to B. Maskit which states a necessary and sufficient condition for the double oriented cover of a planar compact Klein surface of algebraic genus at least two to be a hyperelliptic Riemann
