Functional Inequalities for doubly weighted Brownian Motion with Sticky-Reflecting Boundary Diffusion
Marie Bormann
We give upper bounds for the Poincaré and Logarithmic Sobolev constants for doubly weighted Brownian motion on manifolds with sticky reflecting boundary diffusion under curvature…

A Cheeger-type inequality for the drift Laplacian with Wentzell-type boundary condition
Marie Bormann
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 bul…
