Eigenvalue Estimates on Bakry-Emery Manifolds

11 Dec 2020 · Nelia Charalambous, Zhiqin Lu, Julie Rowlett ·

We demonstrate lower bounds for the eigenvalues of compact Bakry-Emery manifolds with and without boundary. The lower bounds for the first eigenvalue rely on a generalised maximum principle which allows gradient estimates in the Riemannian setting to be directly applied to the Bakry-Emery setting. Lower bounds for all eigenvalues are demonstrated using heat kernel estimates and a suitable Sobolev inequality.
