Abstract
Let \(\Omega \subset \mathbb {R}^{d+1}\), \(d \ge 1\), be a uniform domain with lower d-Ahlfors–David regular and d-rectifiable boundary. We show that if the d-Hausdorff measure \(\mathcal {H}^d|_{\partial \Omega }\) is locally finite, then \(\mathcal {H}^d|_{\partial \Omega }\) is absolutely continuous with respect to harmonic measure for \(\Omega \).
