A note on principal parts on projective space and linear representations

Let be a closed subgroup of a linear algebraic group defined over a field of characteristic zero. There is an equivalence of categories between the category of linear finite-dimensional representations of , and the category of finite rank -homogeneous vector bundles on . In this paper we will study this correspondence for the sheaves of principal parts on projective space, and we describe the representation corresponding to the principal parts of a line bundle on projective space.
