F为环R的滤链,M={Mn}n≥0为一个Cohen-Macaulay模M的HilbertF-滤链,我们证明了ei(F,M)≥e0(F,M)-λ(M/(M)1),并且刻画了等式成立的状况.
F為環R的濾鏈,M={Mn}n≥0為一箇Cohen-Macaulay模M的HilbertF-濾鏈,我們證明瞭ei(F,M)≥e0(F,M)-λ(M/(M)1),併且刻畫瞭等式成立的狀況.

Let F be a filtration of ring R and M={Mn}n≥0 be a Hilbert F-filtration with respect to a Cohen-Macaulay R-module M. We show that e1 (F,M) ≥e0 (F,M) -λ(M/(M)1) and characterize the condition that the equality holds.
