|Abstract:||Let (S, Δ) be a log surface with at worst log canonical singularities and reduced boundary Δ such that -(Ks + Δ) is nef and big. We shall prove that S° = S -SingS - Δ either has finite fundamental group or is affine-ruled. Moreover, π1 (S°) and the structure of S are determined in some sense when Δ = 0. © 1996 American Mathematical Society.|
