Gorenstein Log del Pezzo Surfaces, II Original Research Article

A projective normal surface is a Gorenstein log del Pezzo surface if it has only rational double singularities and the anticanonical divisor is ample. The fundamental group of the smooth part of such a surface is determined. The present article is a sequel to (M. Miyanishi and D.-Q. Zhang. J. Algebra118 (1988), 63-84).
