We study the Hilbert polynomials of finitely generated graded algebras R, w
ith generators not all of degree one (i.e. non-standard). Given an expressi
on P(R, t) = a(t)/(1 - t(l))(n) for the Poincare series of R as a rational
function, we study for 0 less than or equal to i less than or equal to l th
e graded subspaces circle plus(k)R(kl+i) (which we denote R[l; i]) of R, in
particular their Poincare series and Hilbert functions. We prove, for exam
ple, that if R is Cohen-Macaulay then the Hilbert polynomials of all non-ze
ro R[l; i] share a common degree. Furthermore, if R is also a domain then t
hese Hilbert polynomials have the same leading coefficient.
