Remarks on numerically positive line bundles on normal surfacesErika Emura and Hideo KojimaNiigata High School, Niigata, Japan; Department of Information Engineering, Faculty of Engineering, Niigata University, Niigata 950-2181, Japan, e-mail: kojima@ie.niigata-u.ac.jpAbstract: Let $L$ be a numerically positive Cartier divisor on a normal complete algebraic surface $X$. We prove that $L$ is ample if $g(L) \leq 1$. Classification (MSC2000): 14C20; 14J26 Full text of the article:
