Abstract

We show that any Lipschitz projection-valued function $p$ on a connected closed Riemannian manifold can be approximated uniformly by smooth projection-valued functions $q$ with Lipschitz constant close to that of $p$. This answers a question of Rieffel.
Keywords: approximation, Lipschitz constant, projection approximation, Lipschitz constant, projection
