Abstract
By a compact Klein surface X, we shall mean a compact surface together with a dianalytic structure on X [1]. A dianalytic homeomorphism of X onto itself will be called an automorphism of X, and we call the automorphism group of X, the full group of automorphisms of X.
In this paper we calculate all groups that are the automorphism group of a compact planar Klein surface of algebraic genus p⩾2. As a consequence of the equivalence between compact bordered Klein surfaces and real algebraic curves, we calculate all groups that are the automorphism group of an M-real algebraic curve. Some results on automorphism groups of Riemann surfaces of M-curves were obtained by Natanzon in [14].
