关于涉及Hook Weyl模的同态

On homomorphisms involving a hook Weyl module

Mihalis Maliakas, Dimitra-Dionysia Stergiopoulou

摘要:

设$k$是正特征的无限域。我们确定了$GLn(k)$的Weyl模之间的所有同态,其中一个分区是一个钩子。作为结果,我们得到了一个非零的结果,关于同态之间的代数群的B,C和D型时,其中一个分区是一个钩的Weyl模。

英文摘要:

Let $k$ be an infinite field of positive characteristic. We determine all homomorphisms between Weyl modules for $GLn(k)$, where one of the partitions is a hook. As a consequence we obtain a nonvanishing result concerning homomorphisms between Weyl modules for algebraic groups of type B, C and D when one of the partitions is a hook.
