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

open access: yesAnalele 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

open access: yesMathematics
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]

open access: yesJournal 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.

Extremal topologies on a semigroup

open access: yesTopology and its Applications, 1991
Given a semigroup \((S,+)\) with discrete topology \(\tau_ d\), and given a set \({\mathcal A}\) of topologies on \(S\), an element \(\tau\) of \({\mathcal A}\) is said to be extremal (in \({\mathcal A})\) if (i) \(\tau\neq\tau_ d\) and (ii) if \(\tau\subseteq\tau'\in{\mathcal A}\) and \(\tau\neq\tau'\), then \(\tau'=\tau_ d\). The author shows that if

SEMIGROUP ACTIONS , WEAK ALMOST PERIODICITY, AND INVARIANT MEANS [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 1990
Let S be a topological semigroup acting on a topological space X. We develop the theory of (weakly) almost periodic functions on X, with respect to S, and form the (weakly) almost periodic compactifications of X and S, with respect to each other. We then
