New inequalities on the Hadamard product of nonnegative matrices

Year: 2025

Type: article

Abstract: Several novel upper bounds for the spectral radius of the Hadamard product of two nonnegative matrices are presented by leveraging spectral radius properties and the Cauchy-Schwarz inequality. The derived bounds incorporate the maximum values of the non-diagonal elements in each row of the nonnegative matrices. Furthermore, concrete examples are presented to illustrate our results are more accurate than existing relevant results.
