| Abstract: | In this article we prove the following: -
Some results on the Cohen–Macaulayness of the canonical module; -
We study the S 2-fication of rings which are quotients by lattices ideals; -
Given a simplicial lattice ideal of codimension two I, its Macaulayfication is given explicitly from a system of generators of I. |
