On the Lichnerovicz Laplacian

In this paper, we study the geometry of kernel Lichnerovicz Laplacian in case complete and, particular, compact Riemannian manifolds, and also propose a lower estimate its eigenvalues on manifold whose curvature operator is bounded from below an upper with Ricci below. We define space smooth sections bundle covariant tensors as required by original definition; distinguishes our results obtained earlier.
