The BGG correspondence relates complexes over a polynomial ring and complexes over a corresponding exterior algebra. It also leads to exterior algebra methods for computing sheaf cohomology of a sheaf on projective space. I will discuss generalizations of these ideas to products of projective spaces, including a new exterior algebra approach for computing sheaf cohomology on a product of projective spaces. This is joint work with Eisenbud and Schreyer.
