Let $R$ be an open Riemann surface. Among many conformal invariants on $R$, we are interested in quantities derived from some spaces of harmonic functions on $R$, such as spaces of positive harmonic functions, bounded harmonic functions and harmonic Hardy spaces. The classical Harnack distance is one of the important quantities. We compare those invarinats with the hyperbolic distance.
