Smooth Homogenization of Heat Equations on Tubular Neighborhoods
O. Wittich
We consider the heat equation with Dirichlet boundary conditions on the tubular neighborhood of a closed Riemannian submanifold. We show that, as the tube diameter tends to zero, a…

L2-Homogenization of Heat Equations on Tubular Neighborhoods
O. Wittich
We consider the heat equation with Dirichlet boundary conditions on the tubular neighborhood of a closed Riemannian submanifold. We show that, as the tube radius decreases, the sem…

Chernoff's Theorem and Discrete Time Approximations of Brownian Motion on Manifolds
O. G. Smolyanov, H. v. Weizsaecker, O. Wittich
Let (S(t)) be a one-parameter family S = (S(t)) of positive integral operators on a locally compact space L. For a possibly non-uniform partition of [0,1] define a measure on the p…
