Brauer图代数的群作用与覆盖

Group actions and coverings of Brauer graph algebras

Edward L Green, Sibylle Schroll, Nicole Snashall

摘要:

我们发展了一个理论的群作用和覆盖的Brauer图,平行的理论的群作用和覆盖的代数。特别地,我们证明了任何Brauer图都可以被Brauer图的覆盖塔覆盖,使得最上面的覆盖具有重数函数相同的1,没有环,也没有重边。此外,我们分类的覆盖的Brauer图代数,再次Brauer图代数。

英文摘要:

We develop a theory of group actions and coverings on Brauer graphs that parallels the theory of group actions and coverings of algebras. In particular, we show that any Brauer graph can be covered by a tower of coverings of Brauer graphs such that the topmost covering has multiplicity function identically one, no loops, and no multiple edges. Furthermore, we classify the coverings of Brauer graph algebras that are again Brauer graph algebras.
