Brauer代数的共轭及其在character理论中的应用

Conjugation in Brauer algebras and applications to character theory

Armin Shalile

摘要:

布劳尔代数有一个基础的图表和这些产生幺半群$H$组成的标量倍数的图表。根据Kudryavtseva和Mazorchuk最近的一篇论文,我们定义并完全确定了$H$中的三种共轭类型。因此,我们能够定义模块字符的Brauer代数共享许多性质的Brauer字符定义的有限群在一个领域的主要特征。此外,我们重新制定和推广的Brauer代数的普通字符的理论,介绍了拉姆的情况下,Brauer代数是不是半单的。

英文摘要:

The Brauer algebra has a basis of diagrams and these generate a monoid $H$ consisting of scalar multiples of diagrams. Following a recent paper by Kudryavtseva and Mazorchuk, we define and completely determine three types of conjugation in $H$. We are thus able to define modular characters for Brauer algebras which share many of the properties of Brauer characters defined for finite groups over a field of prime characteristic. Furthermore, we reformulate and extend the theory of ordinary characters for Brauer algebras as introduced by Ram to the case when the Brauer algebra is not semisimple.
