Abstract

We state some fundamental properties of the intersection theory for pseudo-effective line bundles defined by Tsuji, and some applications of that theory. As one of applications, we generalize Seshadri's criterion for ampleness of nef line bundles as a criterion for bigness of pseudo-effective line bundles.
