Abstract

Let \fre\fre be a homogeneous subset of \bbR\bbR in the sense of Carleson. Let μ\mu be a finite positive measure on \bbR\bbR and Hμ(x)H_\mu(x) its Hilbert transform. We prove that if limtt\abs\fre{x\absHμ(x)>t}=0\lim_{t\to\infty} t \abs{\fre\cap\{x\mid\abs{H_\mu(x)}>t\}}=0, then μs(\fre)=0\mu_s(\fre)=0, where μ\s\mu_\s is the singular part of μ\mu.
