Let M+ be the maximal operator defined by g MB f(x) = sup ( f(t)lg(t) dt) (f+g(t) dt) where g is a positive locally integrable function on R. We characterize the pairs of nonnegative functions (u, v) for which MB+ applies LP(v) in LP(u) or in weakLp(u) . Our results generalize Sawyer's (case g = 1 ) but our proofs are different and we do not use Hardy's inequalities, which makes the proofs of the inequalities self-contained.
