On the Domain of the Pell-Lucas Matrix in the Spaces c and c_0

Dera Natung Government College Research Journal
In this study, we introduce new Banach sequence spaces $c(\Theta), c_0(\Theta)$, defined via a regular infinite matrix $ \Theta = (\lambda_{nk})$, where \[ \Theta_{nk} = \begin{cases} \dfrac{2\lambda_k}{3\lambda_n+\lambda_{n-1}} & 0 \leq k \leq n ...

Properties of intersection in the geometry of sequences in Banach spaces

Collectanea Mathematica, 1985
We consider properties of sequences in a Banach space through the geometrical behaviour of the closed linear spans of their subsequences. We study new families of intersection properties, generalizing the results of Courage-Davis, Plans, and Reyes. We end with a table showing the structure of a sequence by means of its intersection properties.

On basic sequences in Banach spaces

, 1992
Summary: Let \(X\) be a Banach space with \(X^{**}\) separable. If \(X\) has a shrinking basis and \(Y\) is a closed subspace of \(X^{**}\) which contains \(X\), there exists a shrinking basis \((x_ n)\) in \(X\) with two complementary subsequences \((x_{m_ i})\) and \((x_{n_ j})\) so that \([x_{m_ j}]\) is a reflexive space and \(X+ \widetilde {[x_{n_
