Let [Formula: see text] be a complete CAT(0) space, [Formula: see text] be a closed and convex subset of [Formula: see text] and [Formula: see text] be a multivalued nonexpansive mapping. We prove that the sequence of Ishikawa iteration converges to an endpoint of [Formula: see text]. This improves, extends and unifies some recently announced results of the current literature.
