On the lower bounds for the minimum eigenvalue of the Hadamard product of an M-matrix and its inverse M-matrix

2012
Abstract: In this study, for the minimum eigenvalue 1()AAτ− of the Hadamard product 1AA− of an M-matrix A and its inverse1A− are considered. Some new lower bounds on 1()AAτ− for the Hadamard product of A and 1A− are derived. These bounds improve the results found in [H.B. Li, T.Z. Huang, S.Q. Shen, and H. Li.
