G-matrices
We define a new type of matrix called G-matrix as a real nonsingular matrix. Many special matrices are G-matrices including (generalized) Cauchy matrices and orthogonal matrices. A number of properties of ...

More on G-matrices
The first author and F. J. Hall defined recently a G-matrix as a real nonsingular matrix having the property that the transpose if its inverse can be written as a multiple of the original matrix by nonsingular diag...

G-matrices, J-orthogonal Matrices, and their Sign Patterns
Connections are made between the G-matrices and the J-orthogonal matrices. An investigation into the sign patterns of the J-orthogonal matrices is initiated. Some examples and open questions are provided....

Partial sum of eigenvalues of random graphs
Let G be a graph on n vertices and let lambda(1) >= lambda(2) >= ... >= lambda(n) be the eigenvalues of its adjacency matrix. For random graphs we investigate that a typical graph has S-k <= (e(G) +k(2))/(0.99n)(1/2), where...

Matrix representations of third order jet groups
In this paper, faithful matrix representations of the jet groups G^3_n are presented, following a detailed description of their components in block form. Such groups can be used further to study symmetries of differential equations...

Mathematicians in the new, matrix world
The aim of the paper is to introduce new ways of expressing results in matrix theory by selected mathematicians (F. G. Frobenius, A. Capelli, M. Bocher, ...) in the first three decades of the 20th century. Moreover, we describe the ...
