ABSTRACT

Stanley-Reîsner rings and affine semigroup rings are very important subjects of modern commutative algebra (c.f. https://www.w3.org/1998/Math/MathML"> [ 4,22 ] ) https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429175633/5bc16269-a792-4117-a208-ca03c55a3a8d/content/eq5966.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> .
