A Cheeger inequality for the drift Laplacian with Wentzell boundary condition
Abstract We prove lower bounds for the first non-trivial eigenvalue of the drift Laplacian on manifolds with Wentzell-type boundary condition in terms of some Cheeger-type constants for bulk-boundary interactions. Our results are in the spirit of Cheeger’s classical inequality.
