| Abstract: |
| In this paper, we study the four types of eigenvalue problems for the bi-drifting Laplacian. By using the weighted Reilly formula, we get some sharp lower bounds for the first nonzero eigenvalue for these eigenvalue problems on compact smooth metric measure spaces with boundary and under some condition on the m-weighted Ricci curvature, which generalize the corresponding results for the eigenvalues of biharmonic operator. |
