Nonexpansive semigroups in CAT ( κ ) spaces
Shuechin Huang · Fixed Point Theory and Applications · 2014
The main purpose of this paper is to study Browder type convergence theorems for a nonexpansive semigroup with geometric approaches in a space. Besides, we determine a necessary and sufficient condition for convergence of a Browder type iteration associated to a uniformly asymptotically regular nonexpansive semigroup on the unit sphere in an infinite-dimensional Hilbert space.
