对称函数与量子仿射代数的表示

Symmetric Functions and Representations of Quantum Affine Algebras

Vyjayanthi Chari, Michael Kleber

摘要:

研究了量子仿射代数的有限维不可约表示的特征与对称函数环之间的关系。研究了辛和正交李代数的两类表示。一个是通过组合性质定义的,很容易计算;另一个是密切相关的$q=1$极限的“最小仿射”表示的量子仿射代数。我们推测,这两个家庭是相同的,并提出支持的证据和例子。在特殊情况下的最高权是一个多个基本的重量,这减少到一个猜想的基里洛夫和Reshetikhin,最近证明的第一作者。

英文摘要:

We study connections between the ring of symmetric functions and the characters of irreducible finite-dimensional representations of quantum affine algebras. We study two families of representations of the symplectic and orthogonal Lie algebras. One is defined via combinatorial properties and is easy to calculate; the other is closely related to the $q=1$ limit of the ``minimal affinization'' representations of quantum affine algebras. We conjecture that the two families are identical, and present supporting evidence and examples. In the special case of a highest weight that is a multiple of a fundamental weight, this reduces to a conjecture of Kirillov and Reshetikhin, recently proved by the first author.
