the main purpose of this paper is to define a new regular matrix by using fibonacci numbers and to investigate its matrix domain in the classical sequence spaces $ell _{p},ell _{infty },c$ and $c_{0}$, where $1leq p

let g be a simple connected graph and {v1, v2, …, vk} be the set of pendent (vertices ofdegree one) vertices of g. the reduced distance matrix of g is a square matrix whose (i,j)–entry is the topological distance between vi and vj of g. in this paper, we obtain the spectrumof the reduced distance matrix of thorn graph of g, a graph which obtained by attaching somenew vertices to pendent vertice...

In this paper, considering fractional matrix power definition, we define powers of matrixusing exponential and logarithm. Finally present a guide for computingthe matrix.

in this paper, the concept of k-regular fuzzy matrix as a general- ization of regular matrix is introduced and some basic properties of a k-regular fuzzy matrix are derived. this leads to the characterization of a matrix for which the regularity index and the index are identical. further the relation between regular, k-regular and regularity of powers of fuzzy matrices are dis- cussed.

The life of a higher, multicellular organism is essentially bound up with the triad represented by capillaries, extracellular matrix or ground substance, and cells. A cell is capable of functioning only in its surrounding milieu: the structured extracellular space. Contrary to views of cellular pathology which currently predominate, it is not conceptually feasible to artificially separate cellu...
