晶体与D型仿射Hecke代数

Crystals and affine Hecke algebras of type D

Masaki Kashiwara, Vanessa Miemietz

摘要:

Lascoux-Leclerc-Thibon-Ariki理论断言A型仿射Hecke代数的表示的K-群同构于与李代数$g$相关的群的极大幂幺子群上的函数代数,其中$g$是$gl_\infty$或仿射李代数$A^{(1)}_\ell$,并且不可约表示对应于上整体基。最近,N. Enomoto和第一作者提出了对称晶体的概念,并为B型仿射Hecke代数制定了类似的结构。本文对D型仿射Hecke代数的某些不可约表示类给出了类似的结果。D型晶体是B型晶体的双重覆盖。

英文摘要:

The Lascoux-Leclerc-Thibon-Ariki theory asserts that the K-group of the representations of the affine Hecke algebras of type A is isomorphic to the algebra of functions on the maximal unipotent subgroup of the group associated with a Lie algebra $g$ where $g$ is $gl_\infty$ or the affine Lie algebra $A^{(1)}_\ell$, and the irreducible representations correspond to the upper global bases. Recently, N. Enomoto and the first author presented the notion of symmetric crystals and formulated analogous conjectures for the affine Hecke algebras of type B. In this note, we present similar conjectures for certain classes of irreducible representations of affine Hecke algebras of type D. The crystal for type D is a double cover of the one for type B.
