Dera Natung Government College Research JournalThe characterization of compact operators on BK-spaces, which is the basis of this research, makes use of the Hausdorff measure of non-compactness. In this study, the compactness criteria of matrix operators defined on BK-spaces $\ell_p(\mathcal{T})$ and

FilomatIn this article, we introduce Fibo-Pascal sequence spaces PFc and PF0 by utilizing a newly defined Fibo-Pascal matrix PF. It is proved that PFc and PF0 are BK-spaces that are linearly isomorphic to c and c0, respectively. Furthermore, the Schauder basis and ?-, ?-, ?-duals of both the spaces are computed, and certain classes of matrix ...

Mathematics, 2023 In this paper, we investigate the controllability of the system with non-local conditions. The existence of a mild solution is established. We obtain the results by using resolvent operators functions, the Hausdorff measure of non-compactness, and Monch ...

Erratum to: Every Banach space admits a homogenous measure of non-compactness not equivalent to the Hausdorff measure [PDF]
Science China Mathematics, 2019 [1, Theorem 4.4] states that every infinite dimensional Banach space admits a homogenous measure of noncompactness not equivalent to the Hausdorff measure. Howevere, there is a gap in the proof. In fact, we found that [1, Lemma 4.3] is not true. In this erratum, we give a corrected proof of [1, Theorem 4.4].

Sequence spaces derived by the triple band generalized Fibonacci difference operator
Advances in Difference Equations, 2020 In this article we introduce the generalized Fibonacci difference operator F ( B ) $\mathsf{F}(\mathsf{B})$ by the composition of a Fibonacci band matrix F and a triple band matrix B ( x , y , z ) $\mathsf{B}(x,y,z)$ and study the spaces ℓ k ( F ( B ) ) $

On the Hausdorff measure of noncompactness for the parameterized Prokhorov metric [PDF]
Journal of Inequalities and Applications, 2016 We quantify Prokhorov's Theorem by establishing an explicit formula for the Hausdorff measure of non-compactness (HMNC) for the parametrized Prokhorov metric on the set of Borel probability measures on a Polish space. Furthermore, we quantify the Arzelà-Ascoli Theorem by obtaining upper and lower estimates for the HMNC for the uniform norm on the space

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 ...

Compact operators on the Motzkin sequence space $c_0(\mathcal{M})$
Journal of New Results in ScienceThe concept of non-compactness measure is extremely beneficial for functional analysis in theories, such as fixed point and operator equations. Apart from these, the Hausdorff measure of non-compactness also has some applications in the theory of ...
