Title: Semigroups and Lattice Ideals

Abstract: We will develop machinery in order to generalize our previous discussion regarding N^n graded modules and monomial ideals to a more general setting where there is torsion. To do this we introduce the concept of lattice ideals. We will see how to calculate these using matrices that generate the columns of the ambient abelian group.
