Smooth Homogenization of Heat Equations on Tubular Neighborhoods
摘要:
本文考虑了闭黎曼子流形的管状邻域上具有Dirichlet边界条件的热方程。证明了当管径趋于零时,在Sobolev指数任意大的索伯列夫空间中,适当重标重整化半群收敛到极限半群.
英文摘要:
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 suitably rescaled and renormalized semigroup converges to a limit semigroup in Sobolev spaces of arbitrarily large Sobolev index.
