Calculations in new sequence spaces [PDF]

open access: yes, 2007
summary:In this paper we define new sequence spaces using the concepts of strong summability and boundedness of index $p>0$ of $r$-th order difference sequences.

Grand Lebesgue sequence spaces

open access: yes, 2018
We introduce grand Lebesgue sequence spaces and study various operators of harmonic analysis in these spaces, e.g., maximal, convolution, Hardy, Hilbert, and fractional operators, among others.

Duals of vector-valued Köthe function spaces

open access: yes, 1992
Let Λ be a perfect Köthe function space in the sense of Dieudonné, and Λ× its Köthe-dual. Let E be a normed space. Then the topological dual of the space Λ(E) of Λ-Bochner integrable functions equals the corresponding Λ×(E′) if and only if E′ has the ...

On Köthe-Toeplitz duals of some new and generalized difference sequence spaces

open access: yes, 2012
In this paper we de¯ne the sequence spaces 4mv \(∆_m ^{v,r}\)(lꝏ), \(∆_m ^{v,r}\)(c) and \(∆_m ^{v,r}\)(c0), (m ∈ N, r ∈ R), and have studied some of their topological properties and have computed their Köthe-Toeplitz ...

Weighted spaces of holomorphic functions and sequence spaces

open access: yes, 1997
Our aim in this note is twofold. Firstly we show that, given any Köthe echelon space of order one, a weighted limit of Banach spaces of holomorphic functions on the disc can be constructed such that the strong dual of the sequence space is isomorphic to ...
