Strong and ∆-Convergence Theorems for Total Asymptotically Nonexpansive Nonself Mappings in CAT (k) Spaces
Zhaoli Ma, Shih-sen Chang, Lin Wang · 2016
In this paper, we introduce the concept of total asymptotically nonexpansive nonself mappings and prove the demiclosed principle for this kind of mappings in CAT (k) spaces. As a consequence, we obtain convergence theorems of total asymptotically nonexpansive nonself mappings in CAT (k) spaces. Our results extend and improve the corresponding recent results announced by many authors.
