ON FRAME SYSTEMS IN BANACH SPACES
International Journal of Wavelets, Multiresolution and Information Processing, 2009Banach frame systems in Banach spaces have been defined and studied. A sufficient condition under which a Banach space, having a Banach frame, has a Banach frame system has been given. Also, it has been proved that a Banach space E is separable if and only if E* has a Banach frame ({φn},T) with each φnweak*-continuous.

A Banach Space of Distributions (I)
Journal of the London Mathematical Society, 1957Soit \(L\) l'espace des fonctions \(f\) sommables sur un intervalle \(I = [0, c]\), muni de sa norme usuelle, \(\Vert f\Vert = \int_0^c \vert f\vert\,dx\). Posons \(L_k = D^k L\), avec la topologie image de \(0\) de \(L\) par \(D^k\); \((D\) opérateur de dérivation). Il résulte immédiatement de ce que le rapporteur a établi en 1954 [Rend. Mat. Appl. 14,

Functional Inequalities in Banach Spaces and Fuzzy Banach Spaces
2016This paper is a survey on the Hyers–Ulam stability of additive functional inequalities, quadratic functional inequalities, additive ρ-functional inequalities, and quadratic ρ-functional inequalities in Banach spaces and fuzzy Banach spaces. Its content is divided into the following sections: 1. Introduction and Preliminaries.

On reducibility in Banach spaces
2000Summary: Our main result is an extension of some results of \textit{M. T. Jahandideh} [Proc. Am. Math. Soc. 125, No. 9, 2661--2670 (1997; Zbl 0883.47021)] to reducible operators on Banach spaces instead of Banach lattices.
