要：I will discuss the general problem, first considered by Fujita, of deciding whether a holomorphic line bundle (or more generally a (1,1) cohomology class) on a compact complex manifold admits a smooth Hermitian metric with semipositive curvature (resp. a smooth semipositive representative). I will survey some known results on this question, and discuss a new theorem joint with S. Filip.
