# Topological classification of conformal actions on p-hyperelliptic and (q,n)-gonal Riemann surfaces

Ewa Tyszkowska

Abstract. A compact Riemann surface $$X$$ of genus $$g \gt 1$$ is said to be $$p$$-hyperelliptic if $$X$$ admits a conformal involution $$\rho$$ for which $$X / \rho$$ has genus $$p$$. A conformal automorphism $$\delta$$ of prime order $$n$$ such that $$X / \delta$$ has genus $$q$$ is called a $$(q,n)$$-gonal automorphism. Here we study conformal actions on $$p$$-hyperelliptic Riemann surface with $$(q,n)$$-gonal automorphism.

Keywords: $$p$$-hyperelliptic Riemann surface, automorphism of a Riemann surface.
