On the stability of spacelike hypersurfaces
F. Camargo, A. Caminha, H. de Lima +1
In this paper we study the strong stability of spacelike hypersurfaces with constant -th mean curvature in Generalized Robertson-Walker spacetimes of constant sectional curvatur…
Complete Foliations of Space Forms by Hypersurfaces
A. Caminha, P. Sousa, F. Camargo
We study foliations of space forms by complete hypersurfaces, under some mild conditions on its higher order mean curvatures. In particular, in Euclidean space we obtain a Bernstei…
The geometry of closed conformal vector fields on Riemannian spaces
A. Caminha
In this paper we examine different aspects of the geometry of closed conformal vector fields on Riemannian manifolds. We begin by getting obstructions to the existence of closed co…
Minimal Lie group homomorphisms
A. Caminha
Let and be Lie groups furnished with bi-invariant metrics and be a Lie group homomorphism which is also a minimal isometric immersion. If i…
