论文摘要
有两种组合方法可以参数化$ gl_n $和Superbasic $ b $的Aggine deligne-lusztig品种的不可约组件的$ j_b $ -orbits。一种方法是使用Viehmann引入的扩展半模块。另一种方法是使用Kashiwara和Lusztig引入的晶体碱。在本文中,我们使用晶体结构给出了它们之间的明确对应关系。
There are two combinatorial ways of parameterizing the $J_b$-orbits of the irreducible components of affine Deligne-Lusztig varieties for $GL_n$ and superbasic $b$. One way is to use the extended semi-modules introduced by Viehmann. The other way is to use the crystal bases introduced by Kashiwara and Lusztig. In this paper, we give an explicit correspondence between them using the crystal structure.
