| Abstract: | Utilizing two very well known inequalities, we present a sequence of progressively better upper bounds for the Perron root of a nonnegative matrix. Each element in the sequence is a function of the Perron root of the arithmetic symmetrization of a power of matrix. The results are better than one obtained by utilizing the theorem of A. Brauer. |
