RT Journal Article T1 On the number of ovals of a symmetry of a compact Riemann surface A1 Gamboa Mutuberria, José Manuel A1 Bujalance, E. A1 Cirre, Francisco A1 Gromadzki, G. AB The set of stationary points of the anticonformal involution (reflection) of a Riemann surface is called an oval. In this paper the total number of ovals of all reflections on a surface is counted provided the group of conformal automorphisms of the surface is cyclic. The bounds for this number are also given.
