D型层q-Schur代数

Stratifying q-Schur Algebras of Type D

Jie Du, Leonard L. Scott

摘要:

引入了与D型Hecke代数相关联的两类q-Schur代数,并与Geck,Gruber和Hiss [10],[11]中的一类q-Schur代数有关.证明了一类称为q-Schur^{1.5}代数的代数是整自由的,在基变换下是稳定的,并且当基域具有奇特征时是标准分层的.在[10]、[11]的所谓线性素情形下,这三个族都产生Morita等价代数。最后一节讨论一个不同的例子,并推测一般理论的方向。

英文摘要:

Two families of q-Schur algebras associated to Hecke algebras of type D are introduced, and related to a family used by Geck, Gruber and Hiss [10], [11]. We prove that the algebras in one family, called the q-Schur^{1.5} algebras, are integrally free, stable under base change, and are standardly stratified if the base field has odd characteristic. In the so-called linear prime case of [10], [11], all three families give rise to Morita equivalent algebras. A final section discusses a different example, and speculates on the direction of a general theory.
