In the theory of harmonic functions, Bôcher's theorem states that a positive harmonic function in punctured domain (an open domain minus one point in the interior) is a linear combination of a harmonic function in the unpunctured domain with a scaled fundamental solution for the Laplacian in that domain.

Over the past few decades uniformly rectifiability emerged as a natural geometric condition, necessary and sufficient for classical estimates in harmonic analysis, boundedness of singular integrals in L^2, and, in the presence of some background topological assumptions, for suitable scale invariant estimates on harmonic functions closely.
