Abstract: Under mild conditions of topology on the domain $\Omega\subset\mathbb R^n$, the harmonic measure is $A_{\infty}$-absolutely continuous with respect to the surface measure if and only if the boundary ∂Ω is uniformly rectifiable of dimension n − 1.

We shall present the state of the art around the above statement, and then discuss the strategy employed by Guy David, Svitlana Mayboroda, and the speaker to extend this characterization of uniform rectifiability to sets of dimension d < n − 1.
