Semigroups: An Introduction to the Structure Theory – Pierre A. Grillet – Google Books

Archimedean decompositions, a comparatively small part oftoday’s arsenal, have been generalized extensively, as ssemigroups for instance in the upcoming books by Nagy [] and Ciric []. It examines constructions and descriptions of semigroups and emphasizes finite, commutative, regular and inverse semigroups. Additive subsemigroups of N and Nn have close commuyative to algebraic geometry. These areas are all subjects of active research and together account for about half of all current papers on commutative semi groups.

Commutative rings are constructed from commutative semigroups as semigroup algebras or power series rings.
