An Inequality on M-Matrices
Abstract
Let 𝐴𝐴0 be a nonsingular symmetric M-matrix. For a sufficiently large t, 𝐴𝐴𝑡𝑡 = 𝑡𝑡𝑡𝑡 + 𝐴𝐴0 is a
new nonsingular symmetric M-matrix and the following inequalities hold for the sum of the principal minors of
new matrix 𝐴𝐴𝑡𝑡:
�|𝐴𝐴(1)| < �|𝐴𝐴(1,2)|
𝐶𝐶𝑛𝑛
2 𝐶𝐶𝑛𝑛
1
< ⋯ < �|𝐴𝐴(1,2, … , 𝑛𝑛)|. Definition 1: Let 𝐴𝐴 = �𝑎𝑎𝑖𝑖𝑖𝑖� be a real
𝑗𝑗 = 1,2, … , 𝑛𝑛. If 𝑎𝑎𝑖𝑖𝑖𝑖 ≥ 0 then matrix A is
said to be a non-negative matrix
(Gantmacher, 1956).
Definition 2: Let 𝐵𝐵 = �𝑏𝑏𝑖𝑖𝑖𝑖� be a nonnegative an n dimensional square matrix and
I be a n dimensional unit matrix.
