That is, every increasing sequence of left (or right) ideals has a largest element; that is, there exists an n … WebLet R be a commutative noetherian ring. Let n ≥ 0 be an integer. Then the following three conditions are equivalent. The ring R satisfies (Gn−1) and (Sn). For an R-module M one has: M is n-syzygy M is n-torsionfree M satisfies (Sn). For an R-module M one has: M is (n +1)-syzygy M is (n+ 1)-% torsionfree. blust international
