Some Geometric Properties of the Domain of the Double Sequential Band Matrix in the Sequence Space

open access: yesAbstract and Applied Analysis, 2013
The sequence space was introduced by Maddox (1967). Quite recently, the sequence space of nonabsolute type has been introduced and studied which is the domain of the double sequential band matrix in the sequence space by Nergiz and Başar (2012).

On the New Double Binomial Sequence Space

open access: yesTurkish Journal of Mathematics and Computer Science, 2020
The aim of this paper is to present the new double Binomial sequence space $\mathcal{B}_{p}^{r,s}$ which consists of all sequences whose double Binomial transforms of orders $r,s$ ($r$ and $s$ are nonzero real numbers with $r+s \neq 0$) are in the space $\mathcal{L}_p$, where $0<p<\infty$.

The scale-free nature of protein sequence space. [PDF]

open access: yesPLoS ONE, 2018
The sequence space of five protein superfamilies was investigated by constructing sequence networks. The nodes represent individual sequences, and two nodes are connected by an edge if the global sequence identity of two sequences exceeds a threshold ...
