Some Properties of the Schur Multiplier with Algebraic Topological Approach
Behrooz Mashayekhy, Hanieh Mirebrahimi
In this paper, using a relationship between the Schur multiplier of a group , the fundamental group, and the second homology group of the Eilenberg-MacLane space of , we pres…
Some Properties of Finitely Presented Groups with Topological Viewpoints
Behrooz Mashayekhy, Hanieh Mirebrahimi
In this paper, using some properties of fundamental groups and covering spaces of connected polyhedra and CW-complexes, we present topological proof for some famous theorems about…
On Topological Homotopy Groups of -Hawaiian like spaces
Fateme Helen Ghane, Zainab Hamed, Behrooz Mashayekhy +1
By an -Hawaiian like space we mean the natural inverse limit, , where is…
Small loop spaces and covering theory of non-homotopically Hausdorff spaces
Ali Pakdaman, Hamid Torabi, Behrooz Mashayekhy
In this paper we devote to spaces that are not homotopically hausdorff and study their covering spaces. We introduce the notion of small covering and prove that every small coverin…
A Topological Approach to the Nilpotent Multipliers of a Free Product
Behrooz Mashayekhy, Hanieh Mirebrahimi, Zohreh Vasagh
In this paper, using the topological interpretation of the Baer invariant of a group , , with respect to an arbitrary variety , we extend a result…
On H-groups and their applications to topological homotopy groups
Ali Pakdaman, Hamid Torabi, Behrooz Mashayekhy
This paper develops a basic theory of H-groups. We introduce a special quotient of H-groups and extend some algebraic constructions of topological groups to the category of H-group…
