The Translational Hull of a Topological Semigroup [PDF]
This paper is concerned with three aspects of the study of topological versions of the translational hull of a topological semigroup. These include topological properties, applications to the general theory of topological semigroups, and techniques for computing the translational hull. The central result of this paper is that if

In this thesis we consider in detail the following two fundamental problems for semigroup presentations: 1. Given a semigroup find a presentation defining it. 2. Given a presentation describe the semigroup defined by it.

Smarandache U-liberal semigroup structure [PDF]
In this paper, Smarandache U-liberal semigroup structure is given. It is shown that a semigroup S is Smarandache U-liberal semigroup if and only if it is a strong semilattice of some rectangular monoids. Consequently, some corresponding results on normal

Cayley automaton semigroups [PDF]
Let S be a semigroup, C(S) the automaton constructed from the right Cayley graph of S with respect to all of S as the generating set and ∑(C(S)) the automaton semigroup constructed from C(S). Such semigroups are termed Cayley automaton semigroups. For

Extending binary operations to funtor-spaces
Given a continuous monadic functor $T:\mathbf{Comp}\to\mathbf{Comp}$ in the category of compacta and a discrete topological semigroup $X$ we extend the semigroup operation $\varphi:X\times X\to X$ to a right-topological semigroup operation $\Phi:T\beta X\

On disjoint unions of finitely many copies of the free monogenic semigroup [PDF]
Every semigroup which is a finite disjoint union of copies of the free monogenic semigroup (natural numbers under addition) is finitely presented and residually finite.Peer ...

Brandt Extensions and Primitive Topological Inverse Semigroups
We study (countably) compact and (absolutely) 𝐻-closed primitive topological inverse semigroups. We describe the structure of compact and countably compact primitive topological inverse semigroups and show that any countably compact primitive topological

On the closure of the extended bicyclic semigroup
In the paper we study the semigroup $\mathcal{C}_{\mathbb{Z}}$ which is a generalization of the bicyclic semigroup. We describe main algebraic properties of the semigroup $\mathcal{C}_{\mathbb{Z}}$ and prove that every non-trivial congruence $\mathbb{C}$

On the construction of one-parameter semigroups in topological semigroups [PDF]
Let Sbe a topological Hausdorff semigroup and s e S b e a strongly root compact element. Then there are an algebraic morphism /: Q+ U {0} -* S with /(0) = e9 /(I) = s, and a oneparameter semigroup φ:H->S which satisfy the following properties: If K = Π {/( ]0, e[Q): 0 < e < 1}, then K is a compact connected abelian subgroup of ^ ( e ) , ^(0) = e, φ(H ...

This paper aims to study orbital maps in the context of semigroup actions on topological spaces and fiber bundles. It presents results on the behavior of the dynamical objects involved in the theories of attraction and Lyapunov stability under orbital ...
