	abstract = {Let $K$ be an infinite field of positive characteristic. We classify all homomorphisms between Weyl modules for $GL_n(K)$, 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.},
