## We prove the spectral radius inequality ฯ(A for nonnegative matrices using the ideas of Horn and Zhang. We obtain the inequality A โข B ฯ(A T B) for nonnegative matrices, which improves Schur's classical inequality , where โข denotes the spectral norm. We also give counterexamples to two conject
