Ricci curvature and conformality of Riemannian manifolds to spheres

Salem Eljazi, Najoua Gamara, Habiba Guemri

Published 2007-10-10, updated 2008-04-23Version 3

In this paper we give bounds for the first eigenvalue of the conformal Laplacian and the Yamabe invariant of a compact Riemannian manifold, by using conditions on the Ricci curvature and the diameter and deduce certain conditions on the manifold to be conformal to a sphere.
