Biharmonic and biconservative hypersurfaces in space forms

D Fetcu, C Oniciuc - arXiv preprint arXiv:2012.12476, 2020 - arxiv.org
We present some general properties of biharmonic and biconservative submanifolds and
then survey recent results on such hypersurfaces in space forms. We also propose an …

Polyharmonic hypersurfaces into space forms

S Montaldo, C Oniciuc, A Ratto - Israel Journal of Mathematics, 2022 - Springer
In this paper we shall consider polyharmonic hypersurfaces of order r (briefly, r-harmonic
hypersurfaces), where r≥ 3 is an integer, into a space form N m+ 1 (c) of curvature c. For this …

Biconservative surfaces

S Montaldo, C Oniciuc, A Ratto - The Journal of Geometric Analysis, 2016 - Springer
In this work we obtain some geometric properties of biconservative surfaces in a
Riemannian manifold. In particular, we shall study the relationship between biconservative …

On the existence of closed biconservative surfaces in space forms

S Montaldo, A Pampano - arXiv preprint arXiv:2009.03233, 2020 - arxiv.org
Biconservative surfaces of Riemannian 3-space forms $ N^ 3 (\rho) $, are either constant
mean curvature (CMC) surfaces or rotational linear Weingarten surfaces verifying the …

[HTML][HTML] CMC biconservative surfaces in Sn× R and Hn× R

D Fetcu, C Oniciuc, AL Pinheiro - Journal of Mathematical Analysis and …, 2015 - Elsevier
We classify non-minimal biconservative surfaces with parallel mean curvature vector field in
S n× R and H n× R. When these surfaces do not lie in S n or H n and they are not vertical …

A Upadhyay, NC Turgay - Journal of Mathematical Analysis and …, 2016 - Elsevier
In this paper, we study biconservative hypersurfaces of index 2 in E 2 5. We give the
complete classification of biconservative hypersurfaces with diagonalizable shape operator …

[HTML][HTML] New examples of r-harmonic immersions into the sphere

S Montaldo, A Ratto - Journal of Mathematical Analysis and Applications, 2018 - Elsevier
Polyharmonic, or r-harmonic, maps are a natural generalization of harmonic maps whose
study was proposed by Eells–Lemaire in 1983. The main aim of this paper is to construct …

Closed biconservative hypersurfaces in spheres

S Montaldo, C Oniciuc, A Pampano - Journal of Mathematical Analysis and …, 2023 - Elsevier
We characterise the profile curves of non-CMC biconservative rotational hypersurfaces of
space forms N n (ρ) as p-elastic curves, for a suitable rational number p∈[1/4, 1) which …
