Publication status: Selecta Math. 12 (2006), 137-177.

Let (X, A) be a separated differential quasi-coherent
ringed scheme of finite type over a field k. We prove that
there exists a rigid dualizing complex over A. It is
known from earlier work that a rigid dualizing complex exists on
every affine open set in X; the difficulty is how to glue these
affine dualizing complexes into a global one. We accomplish this
using a perverse t-structure on the derived category of bimodules.
