We show strong and convergence for Mann iteration of a multivalued nonexpansive mapping whose domain
is a nonempty closed convex subset of a CAT(0) space. The results we obtain are analogs of Banach space results by
Song and Wang [2009, 2008]. Strong convergence of Ishikawa iteration are also included.
