Oresme Numbers and Associated BK-Sequence Spaces

Iranian Journal of Science
The aim of this research is to present the formulation of a new conservative matrix operator containing non-integer Oresme numbers, to obtain new BK-sequence spaces with the help of domains of this matrix operator on the spaces of convergent and null sequences.

Sum and product of certain BK spaces and matrix transformations between these spaces

Acta Mathematica Hungarica, 2004
The 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 ...

New properties of BK-spaces defined by using regular matrix of Fibonacci numbers

AIP Conference Proceedings, 2016
In 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.

Some topological and geometric properties of a new BK-space derived by using regular matrix of Fibonacci numbers

Linear and Multilinear Algebra, 2016
In the present paper, we introduce the sequence space using a new regular matrix of Fibonacci numbers, where . We investigate its topological properties such as Schauder basis, and duals and its geometric properties like uniformly convex, strictly convex and super-reflexive.

On the solutions of space-time fractional CBS and CBS-BK equations describing the dynamics of Riemann wave interaction

International Journal of Modern Physics B
In this paper, Kudryashov and modified Kudryashov methods are implemented for the first time to compute new exact traveling wave solutions of the space-time fractional [Formula: see text]-dimensional Calogero–Bogoyavlenskii–Schiff (CBS) equation and Calogero–Bogoyavlenskii–Schiff and Bogoyavlensky Konopelchenko (CBS-BK) equation. With the help of wave
