Webfor all x ∈ E, then the projector operator PM: E → E is well-defined. If furthermore the boundary of the closed convex M is a Ck manifold, the projection mapping PM is Ck [Hol73]. If M is no longer convex, versions of these results still hold locally. This is stated precisely in the following lemma, which will be a basic tool afterwards. Web2.2. Manifold learning ¶.
