Minimal martin compactifications of riemann surfaces with densities

Michihiko Kawamura; Mitsuru Nakai; Toshimasa Tada

Given an arbitrary nonnegative locally Holder continuous 2-form P on an arbitrary open Riemann surface R. We will show the existence of an nonnegative C ∞ 2-form Q on R such that Q ≥ P on R and the Martin compactification R ∗ Q of R which is the smallest possible Martin compactification of R.
