Rotational surfaces of constant astigmatism in space forms
Rafael López, Álvaro Pámpano
A surface in a Riemannian space is called of constant astigmatism if the difference between the principal radii of curvatures at each point is a constant function. In this paper we…

Classification of rotational surfaces with constant skew curvature in 3-space forms
Rafael López, Álvaro Pámpano
In this paper, we classify the rotational surfaces with constant skew curvature in -space forms. We also give a variational characterization of the profile curves of these surfa…
