基本经典李超代数的Grothendieck环

Grothendieck rings of basic classical Lie superalgebras

A. N. Sergeev, A. P. Veselov

摘要:

用相应的广义根系明确地描述了基本经典李超代数的有限维表示的Grothendieck环。我们证明了它们可以被解释为权群环中的子环在某些称为Weyl群胚的群胚的作用下是不变的。

英文摘要:

The Grothendieck rings of finite dimensional representations of the basic classical Lie superalgebras are explicitly described in terms of the corresponding generalised root systems. We show that they can be interpreted as the subrings in the weight group rings invariant under the action of certain groupoids called Weyl groupoids.
