Virasoro代数的上同调群成零条件

On the Vanishing of Cohomology Groups of the Virasoro Algebra

本文建立了Virasoro代数的Ext的一个成零条件,从而得到关于它的上同调群的成零条件.

Extending the notion of category ?? of representations of Kac-Moody Lie algebras to the case of the Virasoro algebra, a vanishing theorem for Ext^n and a Vanishing condition of cohomology groups of the Virusoro algebra are obtained.
