Abstract
This paper establishes and investigates a relationship between the space of solutions of a system of constant coefficient partial differential equations and the cohomology (${H^1}$ in particular) of an associated vector bundle/reflexive sheaf on complex projective space. Using results of Grothendieck and Shatz on vector bundles over projective one-space, the case of partial differential equations in two variables is completely analyzed. The final section applies results about vector bundles on higher-dimensional projective spaces to the case of three or more variables.
