A new class of directed trees is introduced. A formula for the group inverse of the matrices associated with any tree belonging to this class is obtained. This answers affirmatively, a conjecture of Catral et al., for this new class.

We obtain formulae for group inverses of matrices that are associated with a new class of digraphs obtained from stars. This new class contains both bipartite and non-bipartite graphs. Expressions for the group inverse of matrices corresponding to do

A real square matrix A is called a Q-matrix if the linear complementarity problem LCP(A,q) has a solution for all q∈Rn. This means that for every vector q, there exists a vector x≥0 such that y=Ax+...

For real square matrices F , G of the same size with F ≤ G , consider the matrix interval [ F , G ] : = { X : F ≤ X ≤ G } , where the order is defined element wise. It is well known that F and G are invertible M-matrices if, and only if, any ma

In the literature on nonnegative matrix theory, real square invertible matrices with the property that their inverses are M-matrices have been extensively studied. Real square (group invertible) singular M-matrices whose group inverses are M-matrices

Glioblastoma multiforme (GBM) is a highly aggressive type of brain tumor with an extremely poor prognosis. Recent evidences have shown that the “biomechanical imbalances” induced in GBM patient-derived glioblastoma cells (GC) and in vivo via the

Interferon Stimulated Gene (ISG)15 is a ubiquitin-like protein that is induced upon viral infections. Our study reports the identification of two homologues of ISG15 in the Asian seabass designated LcISG15A and LcISG15B. The cloned LcISG15A cDNA frag
