Sharp Estimates for the First Eigenvalues of the Bi-drifting Laplacian
arXiv:1903.06728
Abstract
In the present paper we study some kinds of the problems for the bi-drifting Laplacian operator and get some sharp lower bounds for the first eigenvalue for these eigenvalue problems on compact manifolds with boundary (also called a smooth metric measure space) and weighted Ricci curvature bounded inferiorly.
