Abstract

Let I be the graded ring of homogeneous rational polynomials in n-variables which are numerical over ℤ. Then I is a subring of Γ, the divided polynomial algebra over ℤ in the n-variables. A consequence of the main theorem is that for any positive integer k, the image of the induced homomorphism I[otimes ](ℤ/kℤ) → Γ [otimes ] (ℤ/kℤ) is a finite graded ring.
