Existence of sunny nonexpansive retractions and approximation of fixed points of a representation of nonexpansive mappings

Nonlinear Analysis
This paper presents an implicit scheme for a representation of nonexpansive mappings on a closed convex subset of a smooth uniformly convex Banach space with respect to a left-regular sequence of means defined on a subset of l∞(S).

On some 2-Banach spaces [PDF]

, 2010
The main aim of this article is to introduce some difference sequence spaces with elements in a finite dimensional 2-normed space and extend the notion of 2-norm and derived norm to thus constructed spaces.

On basic sequences in Banach spaces

, 1992
Summary: Let \(X\) be a Banach space with \(X^{**}\) separable. If \(X\) has a shrinking basis and \(Y\) is a closed subspace of \(X^{**}\) which contains \(X\), there exists a shrinking basis \((x_ n)\) in \(X\) with two complementary subsequences \((x_{m_ i})\) and \((x_{n_ j})\) so that \([x_{m_ j}]\) is a reflexive space and \(X+ \widetilde {[x_{n_

On lψ Spaces and infinite.ψ-direct sums of Banach space

, 2011
In this paper, the sequence Banach spaces lψ are defined for a class of convex functions ψ and properties of these spaces and their dual spaces are proved. It can be seen that some well-known sequence Banach spaces are spaces of this type.

Bases in Banach Spaces

, 2018
Countable basis is similar to the usual (Hamel) basis of a vector space; the di erence is that Hamel bases use linear combinations that are nite sums, while for Schauder bases they may be in nite sums.
