Selecting basic sequences in φ-stable Banach spaces [PDF]

open access: yesStudia Mathematica, 2003
Motivated by \textit{B. Maurey's} proof [Math. Sci. Res. Inst. Publ. 34, 149--157 (1999; Zbl 0935.46016)] of \textit{W. T.~Gowers} dichotomy theorem [Geom. Funct. Anal. 6, No. 6, 1083--1093 (1996; Zbl 0868.46007)], the authors prove a quantitative version of this theorem. Let \(\mathcal G_\infty (X)\) denote all closed infinite-dimensional subspaces of

On the analyzing of bifurcation properties of the one‐dimensional Mackey–Glass model by using a generalized approach

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
The goal of this work is to look at how a nonlinear model describes hematopoiesis and its complexities utilizing commonly used techniques with historical and material links. Based on time delay, the Mackey–Glass model is explored in two instances. To offer a range, the relevance of the parameter impacting stability (bifurcation) is recorded.

Isomorphic spectrum and isomorphic length of a Banach space

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2020
We prove that, given any ordinal $\delta < \omega_2$, there exists a transfinite $\delta$-sequence of separable Banach spaces $(X_\alpha)_{\alpha < \delta}$ such that $X_\alpha$ embeds isomorphically into $X_\beta$ and contains no subspace isomorphic to $

Review on Some Sequence Spaces of p-adic Numbers [PDF]

open access: yesEurasian Journal of Science and Engineering, 2017
In this paper, we make a literature review on p-adic sequences and we prove some new topological properties on the sequence spaces w(p), l∞(p) and c(p) of p-adic numbers as the set of all sequences, the set of bounded sequences and the set of convergent ...

New formulas for decreasing rearrangements and a class of Orlicz-Lorentz spaces

open access: yes, 2013
Using a nonlinear version of the well known Hardy-Littlewood inequalities, we derive new formulas for decreasing rearrangements of functions and sequences in the context of convex functions.

Empty-cored sequences in Banach spaces

open access: yesActa et Commentationes Universitatis Tartuensis de Mathematica, 2000
The purpose of the present paper is to describe sequences in Banach spaces in terms of Knopp core. For matrix summability methods, the conditions forcore-shrinkingness are also given. In investigations of core inclusions and several other summability problems in Banach spaces it is vital to be aware ofelements with empty cores.

Exponential Stability of Higher Order Fractional Neutral Stochastic Differential Equation Via Integral Contractors

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6425-6446, April 2025.
ABSTRACT The well‐posedness results for mild solutions to the fractional neutral stochastic differential system with Rosenblatt process with Hurst index Ĥ∈12,1$$ \hat{H}\in \left(\frac{1}{2},1\right) $$ is discussed in this article. To demonstrate the results, the concept of bounded integral contractors is combined with the stochastic result and ...

Spaces of multiplier $ \sigma $-convergent vector valued sequences and uniform $ \sigma $-summability

open access: yesAIMS Mathematics
This study focuses on the development of novel vector-valued sequence spaces whose elements are characterized by constructing (weakly) multiplier $ \sigma $-convergent series.

A Note on the Symmetry of Sequence Spaces [PDF]

open access: yesMathematical Notes, 2019
We give a self-contained treatment of symmetric Banach sequence spaces and some of their natural properties. We are particularly interested in the symmetry of the norm and the existence of symmetric linear functionals.
