Abstract

‎Let $(A,\fm)$ be a commutative quasi-local ring with non-zero identity and let $M$ be an Artinian co-Cohen-Macaulay $R$-module with $\dim M=d$‎. ‎Let $I\subseteq\fm$ be an ideal of $R$ with $\ell(0:_MI)<\infty$‎. ‎In this paper‎, ‎for $0\leq i\leq d$‎, ‎we study the dual of Hilbert coefficients $\acute{e}_i(I,M)$ of $I$ relative to $M$‎. ‎Also‎, ‎we prove the dual of Huckaba-Marley's inequality‎. ‎Moreover‎, ‎we obtain some consequences of this result‎.
