Hausdorff measure of noncompactness of matrix operators on some new difference sequence spaces [PDF]

open access: yesJournal of Inequalities and Applications, 2016
The new sequence spaces X ( r , s , t ; Δ ) $X(r,s,t;\Delta)$ for X ∈ { l ∞ , c , c 0 } $X\in\{l_{\infty}, c, c_{0}\}$ have been defined by using generalized means and difference operator.

On the Hausdorff measure of noncompactness for the parameterized Prokhorov metric [PDF]

open access: yesJournal of Inequalities and Applications, 2016
We quantify the Prokhorov theorem by establishing an explicit formula for the Hausdorff measure of noncompactness (HMNC) for the parameterized Prokhorov metric on the set of Borel probability measures on a Polish space.

Hausdorff measure of noncompactness of matrix mappings on Cesàro spaces

open access: yesBoletim da Sociedade Paranaense de Matemática, 2021
In this study we establish some identities or estimates for operator norms and the Hausdorff measure of noncompactness of certain operators on spaces |C_{α}|_{k}, which have more recently been introduced in [14]. Further, by applying the Hausdorff measure of noncompactness, we establish the necessary and sufficient conditions for such operators to be ...

On composition operators of Fibonacci matrix and applications of Hausdorff measure of noncompactness

open access: yesBoletim da Sociedade Paranaense de Matemática, 2022
The aim of the paper is introduced the composition of the two infinite matrices $\Lambda=(\lambda_{nk})$ and $\widehat{F}=\left( f_{nk} \right).$ Further, we determine the $\alpha$-, $\beta$-, $\gamma$-duals of new spaces and also construct the basis for the space $\ell_{p}^{\lambda}(\widehat{F}).$ Additionally, we characterize some matrix classes on ...

Some notes on matrix mappings and their Hausdorff measure of noncompactness

open access: yesFilomat, 2014
We consider the sequence spaces s0?(?B), s(c)? (?B) and s?(?B) with their topological properties, and give the characterizations of the classes of matrix transformations from them into any of the spaces ?1, ?1, c0 and c. We also establish some estimates for the norms of bounded linear operators defined by those matrix transformations ...
