Improved upper bound for the minimal eigenvalue of the fan product
Year: 2025
Type: conference-paper
Abstract: This note aims to present an improved upper bound for the minimal eigenvalue of the Fan product involving M-matrices employing the non-diagonal elements of two M-matrices and the Fan product trace. Two numerical tests are considered further to verify the effectiveness of the new upper bound.
