Let (A,m) be a commutative quasi-local ring with non-zero identity and let M be an Artinian co-Cohen-Macaulay R-module with NdimM = d. Let I ? m be an ideal of R with ?(0:M I) < ?. In this paper, for 0 ? i ? d, we study the dual of Hilbert coefficients ?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.
