[7]在对域的特征作一定限制的条件下,构造了Bn型Hecke代数的单模.利用An型Hecke代数的第三位作者[13]引入的新思想,我们现在去掉了这些对特征的限制。我们提出了一个模的集合,其中的非零模构成一个两两非同构的单模的完备集。此外,我们制定了一个猜想,哪些模块是非零的。
The simple modules for Hecke algebras of typeBnwere constructed, under certain restrictions on the characteristic of the field, in [7]. Using new ideas, introduced by the third-named author for Hecke algebras of typeAn[13], we now remove these restrictions on the characteristic. We present a collection of modules, of which the non-zero ones form a complete set of pairwise non-isomorphic simple modules. In addition, we formulate a conjecture as to which of the modules are non-zero.
