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 ...

On topological properties of spaces obtained by the double band matrix
Open Mathematics, 2017 Let λ denote any one of the spaces ℓ∞ and ℓp and λ(Ť) be the domain of the band matrix Ť. We study ℓp(Ť) for 1 ≤ p ≤ ∞ and give some inclusions and its topological properties.

A Fourier Analysis Based New Look at Integration
Annales Mathematicae Silesianae, 2023 We approach the problem of integration for rough integrands and integrators, typically representing trajectories of stochastic processes possessing only some Hölder regularity of possibly low order, in the framework of para-control calculus.

Optimal recovery of operator sequences
Математичні Студії, 2021 In this paper we solve two problems of optimal recovery based on information given with an error. First is the problem of optimal recovery of the class $W^T_q = \{(t_1h_1,t_2h_2,\ldots)\,\colon \,\|h\|_{\ell_q}\le 1\}$, where $1\le q < \infty$ and $t_1 ...

Characterizations of Matrix and Compact Operators on BK Spaces
Universal Journal of Mathematics and Applications, 2023 In the present paper, by estimating operator norms, we give some characterizations of infinite matrix classes $\left( \left\vert E_{\mu }^{r}\right\vert _{q},\Lambda\right) $ and $\left( \left\vert E_{\mu }^{r}\right\vert _{\infty },\Lambda\right ...

The T-algebra spectral sequence: Comparisons and applications [PDF]
, 2014 In previous work with Niles Johnson the author constructed a spectral sequence for computing homotopy groups of spaces of maps between structured objects such as G-spaces and E_n-ring spectra.

Anisotropic regularity principle in sequence spaces and applications [PDF]
Communications in Contemporary Mathematics, 2017 We refine a recent technique introduced by Pellegrino, Santos, Serrano and Teixeira and prove a quite general anisotropic regularity principle in sequence spaces.

Communications in Advanced Mathematical Sciences, 2021 In this study, a special lower triangular matrix derived by combining Riesz matrix and Euler totient matrix is used to construct new Banach spaces. $\alpha-$,$\beta-$,$\gamma-$duals of the resulting spaces are obtained and some matrix operators ...

Difference Sequence Spaces Derived by using Pascal Transform
Fundamental Journal of Mathematics and Applications, 2019 The essential goal of this manuscript is to investigate some novel sequence spaces of $p_{\infty }\left( \Delta \right) $, $p_{c}\left( \Delta \right) $ and $p_{0}\left( \Delta \right) $ which are comprised by all sequence spaces whose differences are in
