A Harnack estimate for real normal surface singularities

William Allen Adkins

Vol. 114 (1984), No. 2, 257–265
Abstract

According to Harnack’s theorem the number of topological components of the real part of a nonsingular projective curve X defined over R is at most g(X) + 1, where g(X) is the genus of X. The purpose of the present paper is to present two estimates which can be considered analogs of Harnack’s theorem for normal surface singularities defined over R.
