AbstractUsing an approach of Bergh, we give an alternate proof of Bennett's result on lower bounds for non-negative matrices acting on non-increasing non-negative sequences in lp when p⩾1 and its dual version, the upper bounds when 0<p⩽1. We also determine such bounds explicitly for some families of matrices
