Abstract:

Let $(R, \mathfrak {m})$ be a $d$-dimensional Cohen-Macaulay local ring with infinite residue field. Let $I$ be an $\mathfrak {m}$-primary ideal of $R$. In this paper, we prove that if $\sum _{n=1}^{\infty } \lambda (I^n/I^{n-1}J)-e_1(I)=1$ for some minimal reduction $J$ of $I$, then depth $G(I)\geq d-2$.
