Hecke代数中心的Frobenius映射

Frobenius map for the centers of Hecke algebras

Jinkui Wan, Weiqiang Wang

摘要:

在与n个字母的对称群相关联的Hecke代数的中心的直和Z上引入了一个交换结合分次代数结构。作为Frobenius经典构造的自然变形,我们建立了从代数Z到对称函数环的代数同构。这种同构提供了几个区别基地的中心(介绍了Geck-Rouquier,琼斯,Lascoux)和显式基地的对称函数之间的识别。

英文摘要:

We introduce a commutative associative graded algebra structure on the direct sum Z of the centers of the Hecke algebras associated to the symmetric groups in n letters for all n. As a natural deformation of the classical construction of Frobenius, we establish an algebra isomorphism from the algebra Z to the ring of symmetric functions. This isomorphism provides an identification between several distinguished bases for the centers (introduced by Geck-Rouquier, Jones, Lascoux) and explicit bases of symmetric functions.
