Some Results on Fixed Points and Approximation for a New Class of Mappings in CAT(0) Spaces

preprint2012arXivOpen access

Abstract

We shall generalize the concept of z=(1−t)x⊕tyz=(1-t)x\oplus ty to nn times which contains to verifying some their properties and inequalities in CAT(0) spaces. In the sequel with introducing of αα-nonexpansive mappings, we obtain some fixed points and approximate fixed points theorems.
