Rigidity Results for Spacelike Self-Shrinkers via Different Maximum Principles
Weiller F. Chaves Barboza
In this work, we establish several rigidity results for spacelike self-shrinkers immersed in the pseudo-Euclidean space . Under suitable boundedness conditions…

Rigidity and nonexistence of complete spacelike hypersurfaces in the steady state space
Weiller F. C. Barboza, Henrique F. de Lima, Marco Antonio L. Velásquez
We study complete spacelike hypersurfaces immersed in an open region of the de Sitter space which is known as the steady state space . In…
