Abstract

For ψ ∈ C0 (Rd) and m > 0 we consider the maximal operator given byMm f (x, t) = under(sup, r > 0) | under(∫, Rd) f (x - y, t - | y |m) frac(1, rd) ψ (frac(y, r)) d y | . It is well known that Mm is a Lp-bounded operator for 1 < p ≤ ∞. Also A. Seeger and T. Tao proved that Mm is of weak-type L log log L if m ≠ 1. In this paper we consider the case m = 1 and prove M1 maps the standard Hardy space H1 to weak L1 if d ≥ 4.
