Sub Nearly Uniformly Convex of Orlicz Sequence Spaces Equipped with Luxemburg Norm

open access: yesJournal of Harbin University of Science and Technology, 2022
Nearly uniform noncreasy is a important property in Banach spaces. In this paper we introduce a new geometric property, which is called sub nearly uniformly convex property.

On Approximate Operator Representations of Sequences in Banach Spaces [PDF]

open access: yesComplex Analysis and Operator Theory, 2021
Generalizing results by Halperin et al., Grivaux recently showed that any linearly independent sequence $\{f_k\}_{k=1}^\infty$ in a separable Banach space $X$ can be represented as a suborbit $\{T^{α(k)}φ\}_{k=1}^\infty$ of some bounded operator $T: X\to X.$ In general, the operator $T$ and the powers $α(k)$ are not known explicitly.

Property ( k) of Orlicz Sequence Spaces

open access: yesJournal of Harbin University of Science and Technology, 2017
Property ( k) is an important geometric property in Banach spaces,and it is closely associated with fixed point property. By the geometric theory of Banach spaces and Orlicz spaces, we investigated the characterization for property( k) in a special ...

On spreading $c_0$-sequences in Banach spaces [PDF]

open access: yesStudia Mathematica, 1999
The author introduces the notions of spreading-\((s)\) and spreading-\((u)\). The main results proved: spreading-\((s)\) implies spreading-\((u)\) and some necessary and sufficient conditions for spreading-\((s)\) and spreading-\((u)\).

Weak and strong convergence theorems for relatively nonexpansive mappings in Banach spaces

open access: yesFixed Point Theory and Applications, 2004
We first introduce an iterative sequence for finding fixed points of relatively nonexpansive mappings in Banach spaces, and then prove weak and strong convergence theorems by using the notion of generalized projection.

Generalized quasi-Banach sequence spaces and measures of noncompactness

open access: yesAnais da Academia Brasileira de Ciências, 2013
Given 0 < s ≤ 1 and ψ an s-convex function, s – ψ -sequence spaces are introduced. Several quasi-Banach sequence spaces are thus characterized as a particular case of s – ψ -spaces.

V-Proximal Trustworthy Banach Spaces

open access: yesJournal of Function Spaces, 2020
In a recent work (2016), the first author proved the fuzzy sum rule for the V-proximal subdifferential under some natural assumptions on an equivalent norm of the Banach spaces.

Existence and Uniqueness of Fixed Point for Cyclic Mappings in Quasi-αb-Metric Spaces

open access: yesInPrime, 2022
The fixed point theory remains the most important and preferred topic studied in mathematical analysis. This study discusses sufficient conditions to prove a unique fixed point in quasi-αb-metric spaces with cyclic mapping.
