The purpose of this paper is to study the structure of locally free modules over the ring of differential operators on projective space. Let be a non-singular, complex, algebraic variety. Denote by
the sheaf of rings of differential operators over
and by
its ring of global sections. A
-module M is called locally free if the associated sheaf
⊗ M is locally free as a sheaf of
-modules. Locally free modules arise naturally in
-module theory as inverse images of determined modules; see [1] for definitions and examples.
