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…
Totally Biharmonic Hypersurfaces in Space Forms and 3-Dimensional BCV Spaces
Stefano Montaldo, Alvaro Pampano
A hypersurface is said to be totally biharmonic if all its geodesics are biharmonic curves in the ambient space. We prove that a totally biharmonic hypersurface into a space form i…
Visual Curve Completion and Rotational Surfaces of Constant Negative Curvature
Alvaro Pampano
If a piece of the contour of a picture is missing to the eye vision, then the brain tends to complete it using some kind of sub-Riemannian geodesics of the unit tangent bundle of t…
