超loop代数有限维表示的重数问题
On multiplicity problems for finite-dimensional representations of hyper loop algebras
摘要:
给定一个非代数闭域上的超圈代数,我们讨论有限维表示的交换张量范畴中的多重性问题。也就是说,我们给出了简单对象的l-特征标,Weyl模的Jordan-Holder重数和Clebsch-Gordan系数的公式。
英文摘要:
Given a hyper loop algebra over a non-algebraically closed field, we address multiplicity problems in the underlying abelian tensor category of finite-dimensional representations. Namely, we give formulas for the l-characters of the simple objects, the Jordan-Holder multiplicities of the Weyl modules, and the Clebsch-Gordan coefficients.
