Abstract. Let X be an irreducible, projective variety over a finite field, and let A be a sheaf of rings
on X. In this paper, we study Grothendieck groups of categories of vector bundles over certain types
of ringed spaces (X, A).

0. Introduction
Let X be an irreducible, projective variety over a finite field k of characteristic p.
We write O, (or OX if we need to be more precise), for the structure sheaf of X. In
