Issue Date: | 1996 | Citation: | Zhang, D.-Q. (1996). ALGEBRAIC SURFACES with LOG CANONICAL SINGULARITIES and the FUNDAMENTAL GROUPS of THEIR SMOOTH PARTS. Transactions of the American Mathematical Society 348 (10) : 4175-4184. ScholarBank@NUS Repository. | 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. | Source Title: | Transactions of the American Mathematical Society | URI: | http://scholarbank.nus.edu.sg/handle/10635/102801 | ISSN: | 00029947 |
