摘要: In this paper, using some conditions of (sub) compatibility between a set-valued mapping and a Single-valued mapping, we establish a necessary and sufficient condition and a sufficient condition for set-valued generalized nonexpansive mappings to have a unique common fixed point in complete convex metric spaces. The results improve, extend and develop the main results in [2-7].
