In this paper, we introduce and study a class of new general iteration processes for two finite families of total asymptotically nonexpansive mappings in hyperbolic spaces, which includes asymptotically nonexpansive mapping, (generalized) nonexpansive mapping of all normed linear spaces, Hadamard manifolds and CAT(0) spaces as special cases. Some important related properties to the new general iterative processes are also given and analyzed, and Δ-convergence and strong convergence of the iteration in hyperbolic spaces are proved. Furthermore, some meaningful illustrations for clarifying our results and two open questions are proposed. The results presented in this paper extend and improve the corresponding results announced in the current literature. [ABSTRACT FROM AUTHOR]

In this paper, we introduce a new idea of best proximity point of F-contraction on a closed ball and obtain new theorems in a complete metric space. That is why this outcome becomes useful for contraction of a mapping on a closed ball instead of the whole space.

Our results that have come into being give a proof of extension as well as substantial generalizations and improvements of several well known results in the existing comparable literature.

In this paper, we study mappings f, g, X→P where P is a poset and X is a set, under the relation f≤g, of right parallelism, f(a) ≤ f(b) implies g(a) ≤ g(b), which is reflexive and transitive but not necessarily symmetric. We prove several results of the type: if f has property P and f‖g, then g has property P as well, or of the converse type. Doing so permits us to observe several conditions on mappings and/or groupoids (X,*), upon which mappings may act in particular ways, which are of interest in their own right also. The special case f(x) = x with f ‖ g yielding increasing/non-decreasing mappings g : X → P brings into focus a number of well-known situations seen from a different perspective.

Our results improve and complement several results for cyclic contractions established in [Fixed Point Theory Appl., 2013: 256]. Furthermore, an application to the existence and uniqueness of solution for a class of integral equations is given to illustrate the superiority of the obtained assertions. [ABSTRACT FROM AUTHOR]
