 Thesis  Seminormality and the CohenMacaulay Property
 A Computer Program
This program is devoted to supporting research on the cohomological properties of semigroup rings in Commutative Algebra, Especially focusing on nonnormal semigroup rings. It is written by using Mathematica and works under the Mathematica environment.
This program computes the Hilbert basis of a semigroup, the CohenMacaulay property of a semigroup ring and the type and socle of a standard simplicial CohenMacaulay semigroup ring.
