A remark on homomorphisms between generalized Verma modules
GYOJA1. Let g be a complex simple Lie algebra, Ps a parabolic subalgebra, and f3s the set of (isomorphism classes of) simple us-modules of finite dimension.F or EE),s, put M s(E)= U(g)Ou(p.)E,where U (-) denotes the enveloping algebra.In many cases, it is known thatBased on these results, it was once …
