摘要
Themotivation of this paper is to study a second order elliptic operatorwhich appears naturally in Riemannian geometry, for instance in the study of hypersurfaces with constant r-mean curvature. We prove a generalizedBochner-type formula for such a kind of operators and as applicationswe obtain some sharp estimates for the first nonzero eigenvalues in two special cases. These results can be considered as generalizations of the Lichnerowicz-Obata Theorem. © 2015, Sociedade Brasileira de Matemática.
