Modified Curvatures on Manifolds with Boundary and Applications (1102.3552v1)
Published 17 Feb 2011 in math.PR
Abstract: To study the reflecting diffusion processes on manifolds with boundary, some new curvature operators are introduced by using the Bakry-Emery curvature and the second fundamental form. As applications, the gradient estimates, log-Harnack inequality and Poincar\'e/log-Sobolev inequalities are investigated for the Neumann semigroup on manifolds with boundary.
