A lower bound of the energy functional of a class of vector fields and a characterization of the sphere

Giovanni da Silva Nunes, Jaime Ripoll

Let $M$ be a compact, orientable, $n$ -dimensional Riemannian manifold, $n \geq 2$ , and let $F$ be the energy functional acting on the space $Ξ (M)$ of $C^{\infty}$ vector fields of $…

On the critical points of the energy functional on vector fields of a Riemannian manifold

Giovanni Nunes, Jaime Ripoll

Given a compact Lie subgroup $G$ of the isometry group of a compact Riemannian manifold $M$ with a Riemannian connection $\nabla,$ it is introduced a $G -$ symmetrization process of…
