Covergence of hybrid algorithms for α-nonexpansive mappings in Hilbert spaces
Main Article Content
Abstract
In this paper, we introduce two hybrid algorithms and state their convergence theorems for α -nonexpansive mappings in Hilbert spaces. These results are generalizations of the main ones found in [2]. In addition, we provide illustrations for the obtained results.
