Matrix Inequalities for the Fan Product and the Hadamard Product of Matrices
Dongjie Gao · Advances in Linear Algebra & Matrix Theory · 2015
A new inequality on the minimum eigenvalue for the Fan product of nonsingular M-matrices is given. In addition, a new inequality on the spectral radius of the Hadamard product of nonnegative matrices is also obtained. These inequalities can improve considerably some previous results.
