Uniformizable functional Alexandroff spaces
Fatemah Ayatollah Zadeh Shirazi, Elahe Hakimi, Arezoo Hosseini +1
In the following text we show that the Alexandroff space is uniformizable if and only if the collection of all smallest neighbourhoods is a partition of . Moreover the Alexa…
On pseudo-codecomposition of a transformation group
Safoura Arzanesh, Fatemah Ayatollah Zadeh Shirazi, Reza Rezavand
In the following text we introduce the concept of pseudo-codecomposition of a transformation group, also we show the collection of all transformation groups pseudo-codecomposable t…
Set-theoretical entropies of weighted generalized shifts
Fatemah Ayatollah Zadeh Shirazi, Arezoo Hosseini, Lida Mousavi +1
In this paper for a finite field , a nonempty set , a self--map and a weight vector , we show that the set--theoretical entropy of the weighted…
Module cohomological properties of the Fourier algebra of an inverse semigroup
Massoud Amini, Abasalt Bodaghi, Reza Rezavand
For an inverse semigroup S with the set of idempotents E and a minimal idempotent, we find necessary and sufficient conditions for the Fourier algebra A(S) to be module amenable, m…
