Demiclosedness Principle for Total Asymptotically Nonexpansive Mappings in CAT(0) Spaces

Fixed points for total asymptotically nonexpansive mappings in a new version of bead ‎space‎

The notion of a bead metric space is defined as a nice generalization of the uniformly convex normed space such as $CAT(0)$ space, where the curvature is bounded from above by zero. In fact, the bead spaces themselves can be considered in particular as natural extensions of convex sets in uniformly convex spaces and normed bead spaces are identical with uniformly convex spaces. In this paper, w...

Strong and $Delta$-convergence theorems for total asymptotically nonexpansive mappings in CAT(0)

In this work we use the Noor iteration process for total asymptotically nonexpansive mapping to establish the strong and $Delta$-convergence theorems in the framework of CAT(0) spaces. By doing this, some of the results existing in the current literature  generalize, unify and extend.

Strong and Δ−Convergence for Total Asymptotically Nonexpansive Nonself Mappings in CAT (0) Spaces

In this paper, we prove some strong and Δ−convergence theorems of total asymptotically nonexpansive non-self mappings in CAT (0) spaces. Our results extend and improve the corresponding recent results announced by many authors. Mathematics Subject Classifications: 47H09, 47J25

Existence and convergence of fixed points for mappings of asymptotically nonexpansive type in uniformly convex W-hyperbolic spaces

* Correspondence: zhjx_19@yahoo. com.cn Department of Mathematics, Harbin Institute of Technology, Harbin 150001, PR China Full list of author information is available at the end of the article Abstract Uniformly convex W-hyperbolic spaces with monotone modulus of uniform convexity are a natural generalization of both uniformly convexnormed spaces and CAT(0) spaces. In this article, we discuss ...
