We study p-groups of automorphisms of compact non-orientable Riemann surfaces of topological genus $$g\ge 3$$ g ≥ 3 . We obtain upper bounds of the order of such groups in terms of p, g and the minimal number of generators of the group. We also det

In this article we show that with a few exceptions, every regular dessin d'enfant with genus $g$ having exactly $4g$ automorphisms is embedded in Wiman's curve of type II.

We consider unbranched normal coverings $$X\rightarrow X'$$ between compact Klein surfaces of algebraic genus bigger than one where $$X'$$ is hyperelliptic. Here unbranched means that the fixed point set of the group G of covering transformations is

Let X be a compact Riemann surface of genus $$g \ge 2$$ that possesses a fixed point free group H of automorphisms and let $$Y=X/H$$ denote the orbit space of X under the action of H. Assume Y possesses a symmetry $$\sigma ,$$ that is, an anticonform

If G is a group of automorphisms of a compact Klein surface X, then the direct product G × C 2 is a group of automorphisms of the Riemann double cover X + of X. In this paper we analyse the relationship between G and the full groups of automorphisms

Let S be a compact Riemann surface of genus g > 1 , and let τ : S → S be any anti-conformal automorphism of S, of order 2. Such an anti-conformal involution is known as a symmetry of S, and the species of all conjugacy classes of all symmetries of

We study the question of the extendability of the action of a finite cyclic group on a compact bordered Klein surface (either orientable or non-orientable). This extends previous work by the authors for group actions on unbordered surfaces. It is sho

This paper is devoted to determine the connectedness of the branch loci of the moduli space of non-orientable unbordered Klein surfaces. We obtain a result similar to Nielsen's in order to determine topological conjugacy of automorphisms of prime ord
