On chow groups of G-graded rings

摘要

Let A be a Noetherian ring graded by a finitely generated Abelian group G. It is shown that a Chow group A.(A) of A is determined by cycles and a rational equivalence with respect to certain G-graded ideals of A.. In particular, A.(A) is isomorphic to the equivariant Chow group of A if G is torsion free. References: 7
