On the inverse mean curvature flow by parallel hypersurfaces in space forms
Alancoc dos Santos Alencar, Keti Tenenblat
We consider the inverse mean curvature flow by parallel hypersurfaces in space forms. We show that such a flow exists if and only if the initial hypersurface is isoparametric. The…

On Laguerre Isotropic Hypersurfaces
Fernanda Alves Caixeta, Keti Tenenblat
We study Laguerre isotropic hypersurfaces in the Euclidean space, which are hypersurfaces whose Laguerre form is zero and the eigenvalues of the Laguerre tensor are constant and eq…

Special vector fields on Riemannian manifolds of constant negative sectional curvature and conservation laws
Keti Tenenblat, Alice Barbora Tumpach
We show that any -dimensional Riemannian manifold with constant negative sectional curvature admits local orthonormal vector fields such that one of them is tangent to geo…
