Contact properties of surfaces in r-3 with corank 1 singularities
(Tohoku University, 2015-03-01)
We study the geometry of surfaces in R-3 with corank 1 singularities. At a singular point we define the curvature parabola using the first and second fundamental forms of the surface, which contains all the local second ...

Rigidity theorems for complete spacelike hypersurfaces with constant scalar curvature in De Sitter space
(ELSEVIER SCIENCE BV, 2008)
In this paper we give a partially affirmative answer to the following question posed by Haizhong Li: is a complete spacelike hypersurface in De Sitter space S(1)(n+1)(c), n >= 3, with constant normalized scalar curvature ...
Sobre líneas de curvatura y puntos umbílicos de superficies en R^3
(Universidad de los AndesMatemáticasFacultad de CienciasDepartamento de Matemáticas, 2018)
"Este trabajo expone resultados sobre líneas de curvatura y puntos umbílicos de hipersuperficies y de superficies en R^3 en particular. Entre los resultados expuestos están la clasificación de puntos umbílicos de Darboux, ...
