修正量子包络代数的晶基与双重RSK对应

Crystal bases of modified quantized enveloping algebras and a double RSK correspondence

Jae-Hoon Kwon

摘要:

$A_{+\infty}$或$A_\infty$型的修正量化包络代数的晶体基被实现为一组整数双矩阵。它是通过描述一个最高权晶体和一个最低权晶体的张量积分解成极权晶体,并利用极权晶体的tableaux模型求其极限而得到的。这种实现以一种纯粹的组合方式诱导了修改后的量化包络代数的晶体基的双晶体结构,因此其Peter-Weyl型分解推广了经典的RSK对应。

英文摘要:

The crystal base of the modified quantized enveloping algebras of type $A_{+\infty}$ or $A_\infty$ is realized as a set of integral bimatrices. It is obtained by describing the decomposition of the tensor product of a highest weight crystal and a lowest weight crystal into extremal weight crystals, and taking its limit using a tableaux model of extremal weight crystals. This realization induces in a purely combinatorial way a bicrystal structure of the crystal base of the modified quantized enveloping algebras and hence its Peter-Weyl type decomposition generalizing the classical RSK correspondence.
