论文摘要
我们确定$ \ mathrm {ext} $的尺寸 - 用于复杂的半胶片lie代数和贴载kac-moody algebras的类别$ \ mathcal {o}的单数块中的简单模块和双重概括的Verma模块之间的尺寸。
We determine the dimensions of $\mathrm{Ext}$-groups between simple modules and dual generalized Verma modules in singular blocks of parabolic versions of category $\mathcal{O}$ for complex semisimple Lie algebras and affine Kac-Moody algebras.
