AbstractLet μ be a Borel measure on ℝ. The paper contains the proofs of the estimates and Here A is a subset of ℝ, f is a μ-locally integrable function, μ is the uncentred maximal operator with respect to μ and cp,q, and Cp,q are finite constants depending only on the parameters indicated. In the case when μ is the Lebesgue measure, the optimal choices for cp,q and Cp,q are determined. As an application, we present some related tight bounds for the strong maximal operator on ℝn with respect to a general product measure.

AbstractLet be the dilation group in generated by the infinitesimal generator M where At = exp(M log t), and let be a At-homogeneous distance function defined on . For , we define the maximal quasiradial Bochner-Riesz operator of index δ > 0 byIf At = tI and is a smooth convex hypersurface of finite type, then we prove in an extremely easy way that is well defined on Hp() when δ = n(1/p − 1/2) − 1/2 and 0 < p < 1; moreover, it is a bounded operator from Hp() into Lp,∞().If At = tI and , we also prove that is a bounded operator from Hp() into Lp() when δ > n(1/p − 1/2) − 1/2 and 0 < p < 1.
