Remarks on Mr. Ullemar's second harmonic measure
Mitsuru Ozawa · Kodai Mathematical Journal · 1953
Recently Leo Ullemar has introduced h^s so-called second harmonic measure S2ι in order to give a perfect condition for the existence of Dirichlet-finite automorphic functions.1 ' In this note we shall give an existence proof and establish a simple relation between Sώ and other domain functions.
