Study on generalized BK-5th recurrent Finsler space
Computational Mathematics and its Applications, 2023In this paper, we present a novel new class and investigate the connection between the K-projective curvature tensor and other tensors of Finsler space Fn, this space is characterized by the property for Cartan’s 4th curvature tensor satisfies the certain relationship with the given covariant vectors field, we define this space as a generalized BK-5th

A Class of Reflexive Symmetric Bk-Spaces
Canadian Journal of Mathematics, 1969We denote by ω the linear space of all sequences of real or complex numbers. A linear subspace of ω is called a sequence space. A sequence space E is a BK-space (9) if it is equipped with a norm under which: first, E is a Banach space and second, each of the coordinate maps x → xi is continuous. Let ∑ be the group of all permutations of Z+ = {1, 2, 3, …

A new BK-space defined by regular matrix of Lucas numbers
Journal of Interdisciplinary Mathematics, 2019AbstractThe purpose of this paper is to introduce the Lucas sequence space which is a BK-space with the help of a regular matrix of Lucas numbers for 0 < p < ∞.

New properties of BK-spaces defined by using regular matrix of Fibonacci numbers
AIP Conference Proceedings, 2016In the present paper, we studied the new properties of BK-spaces which were defined using regular matrix of Fibonacci numbers in [1]. We computed alpha-, beta-, gamma- duals of these spaces and obtained Schauder basis. We also derived some topological properties of these spaces.

Sum and product of certain BK spaces and matrix transformations between these spaces
Acta Mathematica Hungarica, 2004The article studies weighted Banach sequence spaces of the type \(s_\alpha = \{(x_n)_{n \in \mathbb N} \in \mathbb C^{\mathbb N}: x_n/\alpha_n \in \ell_\infty\}\) for a weight sequence \(\alpha \in (0,\infty)^{\mathbb N}\), sums and products \(s_\alpha \ast s_\beta =\{ (x_n y_n)_{n \in \mathbb N}: x\in s_\alpha, y\in s_\beta\}\), as well as matrix ...
