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.
