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

open access: yesJournal 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

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.

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.
