As the main result, the possible eigenvalues of a matrix of a system obtained as a result of these connections are determined..
In this paper, the above relation to singular two-parameter eigenvalue problems is extended, and it is shown that the simple finite regular eigenvalues of a two-parameter
The first kind is the minimal and maximal eigenvalues of all leading principal submatrices of A , and the second kind is one eigenvalue of each leading principal submatrix of A

In earlier work, the labelled graphs G for which every combinatorially symmetric totally nonnegative matrix, the graph of whose specified entries is G , has a totally
They introduced the terms “essentially nonnegative matrix” for matrices whose off-diagonal elements are nonnegative and “essentially positive matrix” for essentially
