On the metric projection onto φ-convex subsets of Hadamard manifolds



We introduce the concept of a φ-convex subset of a Hadamard manifold. Then we prove that for a φ-convex subset S of a Hadamard manifold M there exists an open set U containing S such that the metric projection is a single valued locally Lipschitz mapping on U.
