Banach spaces of $\mathcal I$-convergent sequences
, 2023 We study the space $c_{0,\mathcal{I}}$ of all bounded sequences $(x_n)$ that $\mathcal{I}$-converge to $0$, endowed with the sup norm, where $\mathcal{I}$ is an ideal of subsets of $\mathbb{N}$. We show that two such spaces, $c_{0,\mathcal{I}}$ and $c_{0,\mathcal{J}}$, are isometric exactly when the ideals $\mathcal{I}$ and $\mathcal{J}$ are isomorphic.

V-Proximal Trustworthy Banach Spaces
Journal 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.

On spreading $c_0$-sequences in Banach spaces [PDF]
Studia 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-\((u)\).

On some new vector valued sequence spaces $ E(X, \lambda, p) $
AIMS Mathematics, 2023 To define a new sequence space and determine the Köthe-Toeplitz duals of this sequence space, characterizing the matrix transformation classes between the defined sequence spaces and classical sequence spaces has been an important area of work for ...

A study of topological and geometrical characteristics of new Banach sequence spaces
Gulf Journal of Mathematics, 2015 A short extract of this study is to submit a new sequence space ℓp(F(r,s)) under the domain of the matrix F(r,s) constituted by using Fibonacci sequence and non-zero real number r and s of ℓp previously defined.

Existence and Uniqueness of Fixed Point for Cyclic Mappings in Quasi-αb-Metric Spaces
InPrime, 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. The analysis starts by showing

Rosenthal operator spaces [PDF]
, 2007 In 1969 Lindenstrauss and Rosenthal showed that if a Banach space is isomorphic to a complemented subspace of an L_p-space, then it is either a script L_p-space or isomorphic to a Hilbert space.

On some Banach space sequences [PDF]
Bulletin of the Australian Mathematical Society, 1982 We introduce the Banach space of vector valued sequences lp, q(E), 1 ≤ p, q ≤ ∞, where E is a Banach space. Then we study the relation between lp, q(E) and the Schur multipliers of lpE, where E is taken to be some lr.
