Prime ideals and maximal ideals in semigroups
Principal ideals in the semigroup of binary relations on a finite set: What happens when one element is added to the set.
Principal ideals of finitely generated commutative monoids
We study the semigroups isomorphic to principal ideals of finitely generated commutative monoids. We define the concept of finite presentation for this kind of semigroups. Furthermore, we show how to obtain information on these semigroups from their presentations.
