Biconservative Weingarten surfaces with flat normal bundle in
Ştefan Andronic, Stefano Montaldo, Cezar Oniciuc +1
In this paper, we extend our investigation of the class of biconservative surfaces with non-constant mean curvature in 4-dimensional space forms . Specifically, we focus on…

Rigidity results for compact biconservative hypersurfaces in space forms
Ştefan Andronic, Aykut Kayhan
In this paper we present alternative proofs for two known rigidity results concerning non-negatively curved compact biconservative hypersurfaces in space forms. Further, we prove s…

Gap results for biharmonic submanifolds in spheres
Stefan Andronic, Simona Nistor
In this paper we determine a larger gap of the mean curvature for a class of proper biharmonic submanifolds with parallel mean curvature vector field in Euclidean spheres. When the…
