On the strong and Δ-convergence of new multi-step and S-iteration processes in a CAT ( 0 ) space
Metin Başarır, Aynur Şahin · Journal of Inequalities and Applications · 2013
In this paper, we introduce a new class of mappings and prove the demiclosedness principle for mappings of this type in a space. Also, we obtain the strong and Δ-convergence theorems of new multi-step and S-iteration processes in a space. Our results extend and improve the corresponding recent results announced by many authors in the literature. MSC:47H09, 47H10, 54E40, 58C30.
