Patil and Leslie Roberts, accepted. Cohen-Macaulay and Seminormal Affine Semigroups in Dimension Three, Ping Li and Leslie Roberts, in progress. Thesis - Seminormality and the Cohen-Macaulay Property, 2005, Queen's University A Computer Program, Unpublished notes, This program is devoted to supporting research on the cohomological properties of semigroup rings in Commutative Algebra, Especially focusing on non-normal semigroup rings. It is written by using Mathematica and works under the Mathematica environment.
This program computes the Hilbert basis of a semigroup, the Cohen-Macaulay property of a semigroup ring and the type and socle of a standard simplicial Cohen-Macaulay semigroup ring.
