加细的q-三项式系数和character恒等式
Refined q-trinomial coefficients and character identities
摘要：
引入了q-三项式系数的一种改进，它具有非常强大的迭代性质。利用这一“T-不变性”导出了特殊单缀李代数E_6、E_7和E_8的Virasoro特征标恒等式.
英文摘要：
A refinement of the q-trinomial coefficients is introduced, which has a very powerful iterative property. This ``T-invariance'' is applied to derive new Virasoro character identities related to the exceptional simply-laced Lie algebras E_6,E_7 and E_8.
