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.
