摘要
让T = (R M N·S)(θ,ψ)be a左边Noetherian拳台,和M coming right S-module公寓。是proved that max {LGD (R), LGD (S)}≤LGD (T)≤1 + max {LGD (S) + 1, pd (N) + LGD (R / MN)了。
Let T=(R M N S) (θ,ψ) be a left Noetherian ring, and M a flat right S-module. It is proved that max {LGD(R), LGD(S)} ≤LGD(T)≤1+max{LGD(S), 1+pd( s N)+LGD(R/MN)}.
