论文摘要
让$ k $成为一个积极特征的无限领域。我们确定$ gln（k）$的Weyl模块之间的所有同构，其中一个分区是钩子。结果，当分区之一是钩子时，我们获得了B，C和D代数组的Weyl模块之间的同构结果的不变结果。
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.
