A new proof of a characterization of small spherical caps
Rafael López
It is known that planar disks and small spherical caps are the only constant mean curvature graphs whose boundary is a round circle. Usually, the proof invokes the Maximum Principl…
Constant angle surfaces in Minkowski space
Rafael Lopez, Marian Ioan Munteanu
A constant angle surface in Minkowski space is a spacelike surface whose unit normal vector field makes a constant hyperbolic angle with a fixed timelike vector. In this work we st…
Constant Scalar Curvature of Three Dimensional Surfaces Obtained by the Equiform Motion of a Sphere
Fathi M. Hamdoon, Ahmad T. Ali, Rafael Lopez
In this paper we consider the equiform motion of a sphere in Euclidean space . We study and analyze the corresponding kinematic three dimensional surface under the hy…
Minimal translation surfaces in hyperbolic space
Rafael López
In the half-space model of hyperbolic space, that is, $\r^3_{+}=\{(x,y,z)\in\r^3;z>0\}$ with the hyperbolic metric, a translation surface is a surface that writes as …
