An Inequality on M-Matrices

Year 2018, Volume: 44 Issue: 2, 117 - 120, 11.10.2018

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

valued matrix for 𝑖𝑖 = 1,2, … , 𝑚𝑚 and
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.

M-Matrisleri Üzerine Bir Eşitsizlik

Abstract

𝐴𝐴0 tekil olmayan simetrik bir M- matrisi olsun. Yeteri kadar büyük bir t değeri için 𝐴𝐴𝑡𝑡 = 𝑡𝑡𝑡𝑡 + 𝐴𝐴0
şeklinde oluşturulan M- matrisinin esas minörlerinin toplamları arasında
�|𝐴𝐴(1)| < �|𝐴𝐴(1,2)|
𝐶𝐶𝑛𝑛
2 𝐶𝐶𝑛𝑛
1
< ⋯ < �|𝐴𝐴(1,2, … , 𝑛𝑛)|.
𝐶𝐶𝑛𝑛
𝑛𝑛
eşitsizliği vardır.

Selcuk University Journal of Science Faculty accepts articles in Turkish and English with original results in basic sciences and other applied sciences. The journal may also include compilations containing current innovations.

It was first published in 1981 as "S.Ü. Fen-Edebiyat Fakültesi Dergisi" and was published under this name until 1984 (Number 1-4).
In 1984, its name was changed to "S.Ü. Fen-Edeb. Fak. Fen Dergisi" and it was published under this name as of the 5th issue.
When the Faculty of Letters and Sciences was separated into the Faculty of Science and the Faculty of Letters with the decision of the Council of Ministers numbered 2008/4344 published in the Official Gazette dated 3 December 2008 and numbered 27073, it has been published as "Selcuk University Journal of Science Faculty" since 2009.
It has been scanned in DergiPark since 2016.
