Abstract

In this article we prove that the full automorphism group of a cyclic pp-gonal pseudo-real Riemann surface of genus gg is either a semidirect product CnCpC_{n}\ltimes C_{p} or a cyclic group, where pp is a prime >2>2 and g>(p1)2g>(p-1)^{2}. We obtain necessary and sufficient conditions for the existence of a cyclic pp-gonal pseudo-real Riemann surface with full\ automorphism group isomorphic to a given finite group. Finally we describe some families of cyclic pp-gonal pseudo-real Riemann surfaces where the order of the full automorphism group is maximal and show that such families determine some real 2-manifolds embbeded in the branch locus of moduli space.
