A note on starshaped hypersurfaces with almost constant mean curvature in space forms

Julien Roth, Abhitosh Upadhyay

We show that closed starshaped hypersurfaces of space forms with almost constant mean curvature or almost constant higher order mean curvature are closed to geodesic spheres.

Extrinsic eigenvalues upper bounds for submanifolds in weighted manifolds

Fernando Manfio, Julien Roth, Abhitosh Upadhyay

We prove Reilly-type upper bounds for divergence-type operators of the second order as well as for Steklov problems on submanifolds of Riemannian manifolds of bounded sectional cur…

On the relative opers in dimension one

Anoop Singh, Abhitosh Upadhyay

We investigate the relative opers over the complex analytic family of compact complex manifolds of relative dimension one. We introduce the notion of relative opers arising from th…

Isometric immersions into manifolds with metallic structures

Julien Roth, Abhitosh Upadhyay

We consider submanifolds into Riemannian manifold with metallic structures. We obtain some new results for hypersurfaces in these spaces and we express the fundamental theorem of s…

On the geometry of almost Golden Riemannian manifolds

Fernando Etayo, Rafael Santamaría, Abhitosh Upadhyay

An almost Golden Riemannian structure on a manifold is given by a tensor field of type (1,1) satisfying the Golden section relation , and a pure Riemannian m…
