Abstract

We study the existence of a common fixed point for some generalized non-expansive mappings and non-spreading mappings in CAT(0) spaces. We also study an iterative method for approximating common fixed point of a pair of those mappings.

Key words: CAT(0) Space, nonspreading mapping, common fixed  point.
