本文利用B型Hecke代数定义了一个新的类似于Q-Schur代数的代数S。我们证明了S具有与环的选择和参数Q、Q无关的‘类’基。然后构造了S的Weyl模,并得到了定义在任何域上的一族不可约S-模作为因子模。1991年数学学科分类:16G99、20C20、20G05。
In this paper we use the Hecke algebra of type B to define a new algebra S which is an analogue of the q‐Schur algebra. We show that S has ‘generic’ basis which is independent of the choice of ring and the parameters q and Q. We then construct Weyl modules for S and obtain, as factor modules, a family of irreducible S‐modules defined over any field. 1991 Mathematics Subject Classification: 16G99, 20C20, 20G05.
