| Abstract: | The purpose of this paper is to introduce the concepts of H-convex construction and -convex construction and to study the existence of common fixed points and coincidence points for a sequence of set-valued non-expansive mappings in metric Spaces. The results presented in this paper are the generalization of the corresponding results of the single-valued non-expansive mappings. |

| Keywords: | metric space set-valued mapping nonexpansive mapping fixed point coincidence point. |
