在多射影空间上求一个二阶(1,1)的正闭合电流。对于依赖于上同调类ofT的某些值,我们证明了x上超过Lelong数的点的集合具有一定的几何性质。我们还描述了在给定上同调类中具有最大可能Lelong数的电流,以及假定这个数的点的集合。
LetTbe a positive closed current of bidegree (1, 1) on a multiprojective space. For certain values of, which depend on the cohomology class ofT, we show that the set of points ofXwhere the Lelong numbers ofTexceedhave certain geometric properties. We also describe the currentsTthat have the largest possible Lelong number in a given cohomology class, and the set of points where this number is assumed.
