| Abstract: | On a scalar generalized Verma module M(λ)= U(g) ⊗U(p) Cλ, the contravariant forms deeply relate to its structure. In this thesis, we show intrinsically that the contravariant forms have b-functions in its factor in the case where g is simple and the nilpotent radical of p is commutative. As an application we explain intrinsically why the b-functions control the irreducibility of M(λ), the orbit decomposition of n+ under the action of the Levi subgroup, and the unitarizability of the irreducible quotient of M(λ). In addition, we construct an analogue on M(λ) the Capelli identity using our main theorem. |
