Abstract

Let \((R,\mathfrak {m})\) be a d-dimensional Cohen–Macaulay local ring, I an \(\mathfrak {m}\)-primary ideal and J a minimal reduction of I. In this paper we study the independence of reduction ideals and the behavior of the higher Hilbert coefficients. In addition, we also give some examples.
