Abstract: An HD-function (harmonic and Dirichlet-finite) $ \omega $ on a Riemann surface R is called HD-minimal if $ \omega > 0$ and every HD-function $ \omega '$ with $ 0 \leqq \omega ' \leqq \omega $ reduces to a constant multiple of $ \omega $. An $ H{D^ \sim }$-function is the limit of a decreasing sequence of positive HD-functions and $ H{D^\sim}$-minimality is defined as in HD-functions. The purpose of the present note is to answer in the affirmative the open question: Does there exist a Riemann surface which carries an $ HD^\sim $-minimal function but no HD-minimal functions?
