Sequences of bounds for the spectral radius of a positive operator

Functional Analysis 2019-04-04 v1

Abstract

In 1992, Szyld provided a sequence of lower bounds for the spectral radius of a nonnegative matrix AA, based on the geometric symmetrization of powers of AA. In 1998, Ta\c{s}\c{c}i and Kirkland proved a companion result by giving a sequence of upper bounds for the spectral radius of AA, based on the arithmetic symmetrization of powers of AA. In this note, we extend both results to positive operators on L2L^2-spaces.
