A-型Hecke代数的表示

Representations of A-type Hecke algebras

A. P. Isaev, O. Ogievetsky

摘要:

我们回顾了Hecke代数的表示论的一些事实。我们适应的Hecke代数的情况下的方法Okounkov和Vershik这是发达国家的对称群的表示论。我们证明了一个明确的建设的幂等元的Hecke代数的Jucys-Murphy元素。Ocneanu的迹为这些幂等元(这可以解释为q-维的相应的不可约表示的量子线性群)。

英文摘要:

We review some facts about the representation theory of the Hecke algebra. We adapt for the Hecke algebra case the approach of Okounkov and Vershik which was developed for the representation theory of symmetric groups. We justify an explicit construction of the idempotents in the Hecke algebra in terms of Jucys-Murphy elements. Ocneanu's traces for these idempotents (which can be interpreted as q-dimensions of corresponding irreducible representations of quantum linear groups) are presented.
