Stephen Montgomery-Smith, The Hardy Operator and Boyd Indices. Interaction between Probability, Harmonic Analysis and Functional Analysis, Ed: N. Kalton, S.J. Montgomery-Smith, E. Saab, Lecture Notes in Pure and Appl. Math, 175, Marcel Dekker, New York, 1995. We give necessary and sufficient conditions for the Hardy operator to be bounded on a rearrangement invariant quasi-Banach space in terms of its Boyd indices. (tex, dvi, ps, pdf. The LaTeX file also requires the file homegrownmarcdek.sty.)
