Lower bounds on the minimum eigenvalue of the Fan product of several M-matrices
Qin Zhong · Journal of Inequalities and Applications · 2024
Abstract The concept of the Fan product of several M -matrices is introduced. Furthermore, two new lower bounds of the minimum eigenvalue of the Fan product of several M -matrices are proposed. These obtained new lower bounds generalize and improve some earlier findings. One example is presented to illustrate the precision of the given lower bounds.
