Surfaces in a pseudo-sphere with harmonic or 1-type pseudo-spherical Gauss map
Burcu Bektaş, Joeri Van der Veken, Luc Vrancken
We give a complete classification of Riemannian and Lorentzian surfaces of arbitrary codimension in a pseudo-sphere whose pseudo-spherical Gauss maps are of 1-type or, in particula…

Umbilical properties of spacelike co-dimension two submanifolds
Nastassja Cipriani, José M. M. Senovilla, Joeri Van der Veken
For Riemannian submanifolds of a semi-Riemannian manifold, we introduce the concepts of \emph{total shear tensor} and \emph{shear operators} as the trace-free part of the correspon…
