Abstract
Let S + ( D ) S^+(D) denote the space of all positive superharmonic functions on a domain D ⊂ R n D \subset \mathbf R^n . Lindqvist showed that log S + ( D ) \log S^+(D) is a bounded subset of B M O ( D ) BMO(D) . Using this, we give a characterization of finitely connected 2 2 -dimensional uniform domains and remarks on Hölder domains.
