Umbilicity of constant mean curvature hypersurfaces into space forms
A. C. Bezerra, F. Manfio
In this paper we establish conditions on the length of the traceless part of the second fundamental form of a complete constant mean curvature hypersurface immersed in a space of c…
Immersion of gradient almost Yamabe solitons into warped product manifolds
W. Tokura, L. Adriano, E. Batista +1
The purpose of this article is to study the geometry of gradient almost Yamabe solitons immersed into warped product manifolds whose potential is given by the he…
Rigidity and stability estimates for minimal submanifolds in the hyperbolic space
Adriano Cavalcante Bezerra, Fernando Manfio
In this paper we establish conditions on the length of the second fundamental form of a complete minimal submanifold in the hyperbolic space in order to sh…
Sharp Estimates for the First Eigenvalues of the Bi-drifting Laplacian
Adriano Cavalcante Bezerra, Changyu Xia
In the present paper we study some kinds of the problems for the bi-drifting Laplacian operator and get some sharp lower bounds for the first eigenvalue for these eigenvalue proble…
