The idea of applying analytical methods to the theory of polynomial identities appeared in the early 1970s and this approach has become one of the most powerful tools of the theory. A PI-algebra is any algebra satisfying at least one nontrivial polynomial identity.

Recall that the Hilbert polynomial of a coherent sheaf Fon X may be deﬁned as P F(d) := c(X,F(d)) := n å i=0 ( 1)ihi(X,F(d))1 1It is not a priori clear that this is a polynomial n. To prove this, one can induct on the dimension of X and
