我们按照Frenkel和埃尔南德斯(Math Ann,即将发表)以及Frenkel和Reshetikhin(Commun Math Phys 197(1):1-32,1998)的精神,描述了量子仿射代数的有限维表示的q-特征标与其朗兰兹对偶之间的对应(或对偶)。证明了Kirillov-Reshetikhin模及其不可约张量积的对偶性。在证明过程中,我们引入并构造了依赖于两个参数的“插值(q,t)-特征标”,它们插值于量子仿射代数及其Langlands对偶的q-特征标之间。
We describe a correspondence (or duality) between theq-characters of finite-dimensional representations of a quantum affine algebra and its Langlands dual in the spirit of Frenkel and Hernandez (Math Ann, to appear) and Frenkel and Reshetikhin (Commun Math Phys 197(1):1–32, 1998). We prove this duality for the Kirillov–Reshetikhin modules and their irreducible tensor products. In the course of the proof we introduce and construct “interpolating (q,t)-characters” depending on two parameters which interpolate between theq-characters of a quantum affine algebra and its Langlands dual.
