Moore–Penrose inverse of tensors via Einstein product
TL;DR: In this article, the Moore-Penrose inverse of tensors with the Einstein product is defined and the explicit formulas of the MPN inverse of some block tensors are obtained.
Journal ArticleDOI
Some results on resistance distances and resistance matrices
TL;DR: In this paper, an application of resistance distances to the bipartiteness of graphs is given, and an interlacing inequality for eigenvalues of the resistance matrix and the Laplacian matrix is given.
Journal ArticleDOI
Brualdi-type eigenvalue inclusion sets of tensors
TL;DR: By using digraphs of tensors, the authors gave Brualdi-type eigenvalue inclusion sets for tensors and also gave some applications of their result to nonsingularity and positive definiteness.
Journal ArticleDOI
Some characterizations of M-tensors via digraphs
TL;DR: For a tensor A = (a i 1 ⋯ i m ) ∈ C n × ⋩ × n, the associated digraph of A has the vertex set V ( A ) = { 1, …, n }, and the arc set of Γ A is E ( A) = { ( i, j ) | a i i 2 ⋌ i m ≠ 0, j ∈ { i 2, …, i m } ≠ { i, …-, i m ∈ [ i,, j ] ≠
Journal ArticleDOI
Formulas for the drazin inverse of matrices over skew fields
TL;DR: In this paper, the explicit formulas for the Drazin inverse of the block matrices were given when $PQ^2 = 0, $P^2QP = 0.
