A lower bound for the Perron root of a nonnegative matrix

Abstract

AbstractIt is well known that the Perron root r(A) of a nonnegative matrix A lies between the smallest and the largest row sum of A. We obtain a new lower bound for r(A) by using a result of Kuharenko concerning a spectral property of a zero-trace matrix
