Finitely Generated Semigroups
This chapter contains basic properties of finitely generated commutative semigroups: Rédei’s Theorem, various finiteness properties, and the Completion Theorem. The results indicate that these semigroups are assembled somehow from cancellative semigroups and nilsemigroups, arranged along a finite semilattice. This similarity to finite semigroups is pursued much further in the next chapter.
