A geometrical characterization of Schauder basis [PDF]

open access: yesArchiv der Mathematik, 1980
Concerning basis in a Banach space, a characterization for a weak basis to be a Schauder basis is given in terms of the geometrical behavior of the set of linear, closed hulls wich are generated by subsequences of the expansion sequences of the basis.

Adaptive sequential design for regression on Schauder Basis [PDF]

open access: yes, 2008
We present a new sequential algorithm to build both optimal design and model selection in a multi-resolution family of functions. This algorithm relies on a localization property of discrete sequential D and A-optimal designs for Schauder Basis. We use these property with a simulated annealing strategy to obtain our stochastic algorithm.

Schauder basis in a locally k-convex space and perfect sequence spaces [PDF]

open access: yesProyecciones (Antofagasta), 2011
In this work, we are dealing with the natural topology in a perfect sequence space and the transfert of topologies of a locally K — convex space E with a Schauder basis (ei )i to such Space. We are also interested with the compatible topologies on E for which the basis(ei )i is equicontinuous, and the weak basis problem.

Uniformly factoring weakly compact operators and parametrised dualisation

open access: yesForum of Mathematics, Sigma, 2021
This article deals with the problem of when, given a collection $\mathcal {C}$ of weakly compact operators between separable Banach spaces, there exists a separable reflexive Banach space Z with a Schauder basis so that every element in $\mathcal {C ...

On Λ-Fibonacci difference sequence spaces of fractional order

open access: yesDera Natung Government College Research Journal, 2021
In this article, we introduce -Fibonacci difference operator of fractional order  which is obtained by the composition of -Fibonacci matrix  and backward fractional difference operator  defined by  and introduce the sequence spaces  and  We give some ...

Constraint Qualification with Schauder Basis for Infinite Programming Problems

open access: yesApplied Mathematics & Optimization, 2023
AbstractWe consider infinite programming problems with constraint sets defined by systems of infinite number of inequalities and equations given by continuously differentiable functions defined on Banach spaces. In the approach proposed here we represent these systems with the help of coefficients in a given Schauder basis.

Some New Cauchy Sequence Spaces

open access: yesUniversal Journal of Mathematics and Applications, 2018
In this paper, our goal is to introduce some new Cauchy sequence spaces. These spaces are defined by Cauchy transforms. We shall use notations $C_{\infty }\left( s,t\right) $, $C\left( s,t\right) $ and $C_{0}\left( s,t\right) ~$for these new sequence ...

The Application Domain of Infinite Matrices with Algorithms

open access: yesUniversal Journal of Mathematics and Applications, 2018
The purpose of this paper is twofold. First, we define the new spaces and investigate some topological and structural properties. Also, we compute dual spaces of new spaces which are help us in the characterization of matrix mappings.
