Generalizations of S leszyn ski Pringheim's convergence criteria for ordinary continued fractions are proved for noncommutative continued fractions in Banach spaces. Some of them are exact generalizations of the scalar results.

โฆ Synopsis
In this paper, we study continuity properties of the mapping P: (x, A) ร P A (x) in a nonreflexive Banach space where P A is the metric projection onto A. Our results extend the existing convergence theorems on the best approximations in a reflexive Banach space to nonreflexive Banach spaces by using Wijsman convergence of sets.

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
A reduction theorem for systems of differential equations with impulse effect at fixed moments in a Banach space is proven. This result allows one to substantially reduce the given system to a much simpler one.
A new iterative method is constructed which converges strongly to the unique solution of the equation Ax s f. Our work extends some of the known results due to Chidume and Osilike, and Chidume and Aneke.
