New Results on the SSIE with an Operator of the form FΔ ⊂ Ɛ + Fx′ Involving the Spaces of Strongly Summable and Convergent Sequences Using the Cesàro Method

open access: yesAxioms, 2021
Given any sequence a=(an)n≥1 of positive real numbers and any set E of complex sequences, we can use Ea to represent the set of all sequences y=(yn)n≥1 such that y/a=(yn/an)n≥1∈E.

Large-conductance Ca2+-activated potassium channels are potently involved in the inverse neurovascular response to spreading depolarization

open access: yesNeurobiology of Disease, 2018
Recurrent spreading depolarizations occur in the cerebral cortex from minutes up to weeks following acute brain injury. Clinical evidence suggests that the immediate reduction of cerebral blood flow in response to spreading depolarization importantly ...

On some BK spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
We characterize the spaces sα(Δ), , and and we deal with some sets generalizing the well‐known sets w0(λ), w∞(λ), w(λ), c0(λ), c∞(λ), and c(λ).

The Hausdorff measure of noncompactness of matrix operators on some BK spaces [PDF]

open access: yesOperators and Matrices, 2011
In the present paper, we establish some identities or estimates for the operator norms and the Hausdorff measures of noncompactness of certain matrix operators on the spaces c0 and ∞ which have recently been introduced in [On the spaces of λ -convergent and bounded sequences, Thai J. Math. 8(2) (2010) 311–329].

Weighted almost convergence and related infinite matrices

open access: yesJournal of Inequalities and Applications, 2018
The purpose of this paper is to introduce the notion of weighted almost convergence of a sequence and prove that this sequence endowed with the sup-norm ∥ ⋅ ∥ ∞ ${\Vert \cdot \Vert } _{\infty}$ is a BK-space. We also define the notions of weighted almost
