Conformal Vector Fields and the De-Rham Laplacian on a Riemannian Manifold with Boundary

Antônio Freitas, Israel Evangelista, Emanuel Viana

Let $(M^{n}, g)$ be an $n$ -dimensional compact connected Riemannian manifold with boundary. In this article, we study the effects of the presence of a nontrivial conformal vector fiel…

Conformal gradient vector fields on Riemannian manifolds with boundary

Israel Evangelista, Emanuel Viana

Let $(M^{n}, g)$ be an $n$ -dimensional compact connected Riemannian manifold with smooth boundary. We show that the presence of a nontrivial conformal gradient vector field on $M$ , wi…
