摘要
For the classical Hardy-Littlewood maximal function Mf, a well known and important estimate due to Herz and Stein gives the equivalence (Mf)*(t) similar to f**(t). In the present note, we study the validity of analogous estimates for maximal operators of the form [GRAPHICS] where parallel to . parallel to(p,q) denotes the Lorentz space L(p, q)-norm.
