β¦ Synopsis
In this paper we study spaces of mappings A : K Βͺ K satisfying Ax s x for all x g F, where K is a closed convex subset of a hyperbolic complete metric space and F is a closed convex subset of K. These spaces are equipped with natural Ε½ . complete uniform structures. We study the convergence of powers of F -attracting Ε½ . mappings as well as the convergence of infinite products of uniformly F -attract-Ε½ . ing sequences and show that if there exists an F -attracting mapping, then a Ε½ . generic mapping is also F -attracting. We also consider a finite sequence of subsets F ; K, i s 1, . . . , n, with a nonempty intersection F and a certain regulari Ε½ . ity property and show that if each mapping A is F -attracting, i s 1, . . . , n, then i i Ε½ . their product and convex combinations are F -attracting.

Let C be a closed, convex subset of a uniformly convex Banach space whose norm is uniformly Ga^teaux differentiable and let T be an asymptotically nonexpansive mapping from C into itself such that the set F(T ) of fixed points of T is nonempty. In this paper, we show that F(T ) is a sunny, nonexpans
We extend the classical inverse and implicit function theorems, the implicit function theorems of Lyusternik and Graves, and the results of Clarke and Pourciau to the situation when the given function is not smooth, but it has a convex strict prederivative whose measure of noncompactness is smaller
In this paper we study the relation between invariant submean and normal structure in a Banach space. This is used to give an improvement and different proof of a fixed point theorem of Lim (also of Belluce and Kirk for commutative semigroups) for left reversible semigroup of nonexpansive mappings o
