Abstract
In this paper we study the scalar generalized Verma module associated to a character of a parabolic subgroup of . Here is a finite dimensional vector space over an algebraically closed field of characteristic zero. The Verma module has a canonical simple quotient with a canonical filtration . In the case when the quotient is finite dimensional we use left annihilator ideals in and geometric results on jet bundles to generalize to an algebraically closed field of characteristic zero a classical formula of W. Smoke on the structure of the jet bundle of a line bundle on an arbitrary quotient where is a parabolic subgroup of . This formula was originally proved by Smoke in 1967 using analytic techniques.
