NEW BOUNDS FOR EIGENVALUES OF THE HADAMARD PRODUCT AND THE FAN PRODUCT OF MATRICES
Guanghui Cheng · Taiwanese Journal of Mathematics · 2014
In this paper, we proposed some lower bounds for the minimum eigenvalue of the Fan product of $M$-matrices, and a upper bound for the spectral radius of the Hadamard product of nonnegative matrices. These improve two existing results. To illustrate our results, two simple examples are considered.
