 Semipositive line bundles and (1,1) classes

  2017.08.23(星期三),10:00-11:00

  点:数学院南楼N913

  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.
