Demiclosed Principle and Δ-Convergence of Fixed Points for Total Asymptotically Nonexpansive Mappings in Hyperbolic Spaces

Li-Li Wan · Journal of Advances in Mathematics and Computer Science · 2015

In this paper, we prove the existence of fixed points and demiclosed principle for total asymptotically nonexpansive mappings in hyperbolic spaces. As a consequence, we obtain a Δ-convergence theorem for such mappings in hyperbolic spaces. Our results improve and extend some resu...
