In this work we will find the minimun genus of a compact non orientable Riemann Surface, having a. given. Cyclic group of . automorphisms . For this we caracterize the proper N. E. C . groups for which there is a non-orientable Surface-Kernel homomorphism . In the last part of this paper we give a bound depending on: the genus, for the order of the cyclic groups of automorphisms of compact Klein Surfaces without boundary, and cyclic groups of automorphisms reaching the bound are obtained.
