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…
