A note on area estimates for stable -hypersurfaces and applications
Marcos Ranieri, Elaine Sampaio, Feliciano Vitório
We show some area estimates for stable CMC hypersurfaces immersed in Riemannian manifolds with scalar and sectional curvature bounded from below. In particular, we focus on immersi…
