摘要

g\mathfrak{g} 为复单李代数,Uq(g^)U_q(\hat{\mathfrak{g}}) 为相应的量子仿射代数。我们证明每个不可约有限维 Uq(g^)U_q(\hat{\mathfrak{g}})-模都会产生一族 Cherednik 广义反射方程的三三角解。这些解依赖于量子仿射对称对 Uq(k)Uq(g^)U_q(\mathfrak{k})\subset U_q(\hat{\mathfrak{g}}) 的选择。我们的结果依赖于先前工作中得到的任意量子对称对的泛 K-矩阵构造,以及每个不可约 Uq(g^)U_q(\hat{\mathfrak{g}})-模在限制到 Uq(k)U_q({\mathfrak{k}}) 时一般为不可约这一事实。在小模与 Kirillov-Reshetikhin 模的情形下,我们得到了标准与转置反射方程的新解。

We added Remark 7.8.2 about a straightforward generalization of Theorem 7.8.1, yielding new solutions of the standard and the transposed reflection equations in the case of a much wider class of irreducible representations. Minor edits. 37 pages
