Multiple gcd-closed sets and determinants of matrices associated with arithmetic functions

Open Mathematics, 2016
Let f be an arithmetic function and S= {x1, …, xn} be a set of n distinct positive integers. By (f(xi, xj)) (resp. (f[xi, xj])) we denote the n × n matrix having f evaluated at the greatest common divisor (xi, xj) (resp. the least common multiple [xi, xj]

Determinants and Inverses of Ppoeplitz and Ppankel matrices

Special Matrices, 2018
In this paper, we consider two kinds of special matrices, which are called Ppoeplitz matrix and Ppankel matrix. The idea of matrix transformation is used to compute the determinants and inverses of the Ppoeplitz matrix and the Ppankel matrix.

The coherence between PSMC6 and α-ring in the 26S proteasome is associated with Alzheimer’s disease

Frontiers in Molecular Neuroscience
Alzheimer’s disease (AD) is a heterogeneous age-dependent neurodegenerative disorder. Its hallmarks involve abnormal proteostasis, which triggers proteotoxicity and induces neuronal dysfunction.

Determinant Theory for Neutrosophic Hypersoft Rough Fuzzy Matrices [PDF]

Neutrosophic Sets and Systems
In this study, we examine the determinant theory associated with Neutrosophic Hypersoft Rough Fuzzy Matrices (NHSRFMs) and investigate several of their structural properties.

Determinant Theory of Quadri-Partitioned Neutrosophic Fuzzy Matrices and its Application to Multi-Criteria Decision-Making Problems [PDF]

Neutrosophic Sets and Systems
We propose a refined method to compute the determinant of matrices with a higher number of rows and columns. Furthermore, an algorithm is developed to address decision-making problems based on QPNFMs.

On Factorization and Calculation of Determinant of Block Matrices with Triangular Submatrices

Journal of New Theory
In this paper, we consider some block matrices of dimension $nm\times{nm}$ whose components are triangular matrices of dimension $n\times{n}$. We prove that the determinant of such block matrices is determined only by the diagonal elements of their ...
