Abstract
AbstractLet (A,${\mathfrak{m}$) be a Cohen–Macaulay local ring of dimensiondand letI⊆Jbe two${\mathfrak{m}$-primary ideals withIa reduction ofJ. Fori= 0,. . .,d, leteiJ(A) (eiI(A)) be theith Hilbert coefficient ofJ(I), respectively. We call the numberci(I,J) =eiJ(A) −eiI(A) theith relative Hilbert coefficient ofJwith respect toI. IfGI(A) is Cohen–Macaulay, thenci(I,J) satisfy various constraints. We also show that vanishing of someci(I,J) has strong implications on depthGJn(A) forn≫ 0.
