Title: Spectral gap estimates for Brownian motion on domains with sticky-reflecting boundary diffusion
Abstract: Introducing an interpolation method we estimate the spectral gap for Brownian motion on general domains with sticky-reflecting boundary diffusion associated to the first nontrivial eigenvalue for the Laplace operator with corresponding Wentzell-type boundary condition. In the manifold case our proofs involve novel applications of the celebrated Reilly formula. (Joint work with Vitalii Konarovskyi and Victor Marx)
The talk will be followed by refreshments in the Huxley Common Room at 4pm.
