In order to prove our main result we develop a theory of proximal calculus in the setting of Riemannian manifolds.engjournal articlehttp://www.sciencedirect.com/science/article/pii/S0362546X06002628restricted access517.988.525Proximal subdifferentialRiemannian manifoldsFixed point theoryAnálisis funcional y teoría de operadores
