CHARACTERIZATIONS OF EXTREMELY AMENABLE FUNCTION ALGEBRAS ON A SEMIGROUP [PDF]

Journal of Sciences, Islamic Republic of Iran, 1993
Let S be a semigroup. In certain cases we give some characterizations of extreme amenability of S and we show that in these cases extreme left amenability and extreme right amenability of S are equivalent.

The topology of the generic polar curve and the Zariski invariant for branches of genus one

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
We study, for plane complex branches of genus one, the topological type of its generic polar curve, as a function of the semigroup of values and the Zariski invariant of the branch.

Graphical Homotopy Theory for Intersection Graphs of Semigroups via Path Spaces and Uniform Structures with Applications to Graphical Total Semigroups

Mathematics
In this article, we study the homotopy aspects of intersection graphs of topological semigroups. We begin by defining the top intersection graph TGX and investigating how the algebraic and topological properties of a topological semigroup are reflected ...

UNIVERSAL COMPACTIFICATIONS OF TRANSFORMATION SEMIGROUPS [PDF]

Journal of Sciences, Islamic Republic of Iran, 2000
We extend the notion of semigroup compactification to the class of transformation semigroups, and determine the compactifications which are universal with respect to some topological properties.

SEMIGROUP COMPACTIFICATION IN AN INTUITIONISTIC FUZZY CONVERGENCE TOPOLOGICAL SPACE

, 2015
The purpose of this paper is to discuss the problem of intuitionistic fuzzy lim semigroup compactification on intuitionistic fuzzy convergence topological semigroup and prove that the set of all intuitionistic fuzzy lim semigroup compactification of an ...

On some generalization of the bicyclic semigroup: the topological version

We show that every Hausdorff Baire topology $tau$ on ${cal C} = langle a,b | a^2b=a, ab^2=b rangle$ such that $({cal C},tau)$ is a semitopological semigroup is discrete and we construct a nondiscrete Hausdorff semigroup topology on ${cal C}$.
