Biconservative and Biharmonic Hypersurfaces in Product Spaces
V. Branding, S. Montaldo, C. Oniciuc +1
In this paper we investigate biconservative and biharmonic hypersurfaces in product spaces , where denotes the space form ${\…
Existence and stability of weak critical points of -energy functionals
Stefano Montaldo, Andrea Ratto, Antonio Sanna
The main aim of this paper is to prove the existence of certain proper weakly -harmonic (-harmonic) maps. We construct critical points which belong to a family of rotation…
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…
Polyharmonic curves in semi-Riemannian manifolds
Stefano Montaldo, Andrea Ratto, Antonio Sanna
Let be a semi-Riemannian manifold of dimension with a non-degenerate metric of \textit{index} , , . The main aim of this paper is to…
An Invitation to Biharmonic and Biconservative Submanifolds
Stefano Montaldo
This note is based on a lecture delivered by the author at the Second Conference on Differential Geometry, held in Fez in October 2024. It offers an accessible introduction to biha…
Conformal-biharmonic hypersurfaces in spheres and product spaces
V. Branding, S. Montaldo, S. Nistor +2
The conformal-bienergy functional is a modified version of the classical bienergy functional and it is conformally invariant in the case of a four-dimensional domain.…
