On conformal biharmonic maps and hypersurfaces
Volker Branding, Simona Nistor, Cezar Oniciuc
In this article we initiate a thorough geometric study of the conformal bienergy functional which consists of the standard bienergy augmented by two additional curvature terms. The…
On the conformal-biharmonic stability of the identity map of Einstein manifolds
Volker Branding, Simona Nistor, Cezar Oniciuc
The identity map of an Einstein manifold is a critical point of both the classical energy functional and the conformal-bienergy functional. In this paper, we investigate the confor…
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.…
Biconservative Weingarten surfaces with flat normal bundle in
Åtefan 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 o…
