A correspondence between a class of monoids and self-similar group actions II
We describe a correspondence between a class of left cancellative monoids and self-similar group actions in the sense of Nekrashevych et al. This correspondence originated in Perrot’s 1972 thesis, and developed the ideas to be found in Rees’ 1948 paper. 2000 AMS Subject Classification: 20M10, 20M50.
متن کاملSelf - similar group actions and a paper of David Rees
We show that David Rees’ 1948 paper on the structure of left cancellative monoids stands at the threshold of the theory of self-similar group actions, and in doing so correct an error in a paper by Nivat and Perrot. 2000 AMS Subject Classification: 20M05, 20M12, 20M18.
متن کاملPrimary ideals of finitely generated commutative cancellative monoids
We give a characterization of primary ideals of finitely generated commutative monoids and in the case of finitely generated cancellative monoids we give an algorithmic method for deciding if an ideal is primary or not. Finally we give some properties of primary elements of a cancellative monoid and an algorithmic method for determining the primary elements of a finitely generated cancellative ...
متن کاملOn Cancellative Set Families
A family of subsets of an n-set is 2-cancellative if for every four-tuple {A, B, C, D} of its members A ∪B ∪C = A ∪B ∪D implies C = D. This generalizes the concept of cancellative set families, defined by the property that A ∪B 6= A ∪C for A, B, C all different. The asymptotics of the maximum size of cancellative families of subsets of an n-set is known, (Tolhuizen [7]). We provide a new upper ...
متن کاملAutomatic Presentations for Cancellative Semigroups
This paper studies FA-presentable structures and gives a complete classification of the finitely generated FA-presentable cancellative semigroups. We show that a finitely generated cancellative semigroup is FA-presentable if and only if it is a subsemigroup of a virtually abelian group.
