WebDec 1, 2014 · Theorem 1. Let M be a closed smooth manifold of dimension n ≥ 5. A homeomorphism φ of M can be approximated uniformly by diffeomorphisms if and only if φ is isotopic to a diffeomorphism. See Section 2 for details. We first reduce the theorem to the case of the unit ball in R n in Section 3, and then prove the local result in Section 4. WebAccording to quasiconformal geometry theorem, each diffeomorphism determines a Beltrami differential on the source surface. Inversely, the diffeomorphism is determined by its Beltrami differential with normalization conditions. ... Surface conformal mapping can be generalized to surface quasiconformal mapping, which has great potential to ...
