چکیده

We characterize the monoid of endomorphisms semigroup all oriented full transformations a finite chain, as well partial and permutations chain. Characterizations monoids subsemigroups orientation-preserving three semigroups aforementioned are also given. In addition, we compute number each these six semigroups.

compactifications and representations of transformation semigroups

this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...

On certain semigroups of transformations that preserve double direction equivalence

Let TX be the full transformation semigroups on the set X. For an equivalence E on X, let TE(X) = {α ∈ TX : ∀(x, y) ∈ E ⇔ (xα, yα) ∈ E}It is known that TE(X) is a subsemigroup of TX. In this paper, we discussthe Green's *-relations, certain *-ideal and certain Rees quotient semigroup for TE(X).

Central Limit Theorem for Commutative Semigroups of Toral Endomorphisms

Abstract. Let S be an abelian finitely generated semigroup of endomorphisms of a probability space (Ω,A, μ), with (T1, ..., Td) a system of generators in S. Given an increasing sequence of domains (Dn) ⊂ N, a question is the convergence in distribution of the normalized sequence |Dn| 12 ∑ k∈Dn f ◦ T , or normalized sequences of iterates of barycenters Pf = ∑ j pjf ◦ Tj, where T k = T k1 1 ...T ...

new semigroup compactifications via the enveloping semigroups of associated flows

this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.

Generating transformation semigroups using endomorphisms of preorders, graphs, and tolerances

Let ΩΩ be the semigroup of all mappings of a countably infinite set Ω. If U and V are subsemigroups of ΩΩ, then we write U ≈ V if there exists a finite subset F of ΩΩ such that the subgroup generated by U and F equals that generated by V and F . The relative rank of U in ΩΩ is the least cardinality of a subset A of ΩΩ such that the union of U and A generates ΩΩ. We study the notions of relative...
