On Baer Invariants of Pairs of Groups
Zohreh Vasagh, Hanieh Mirebrahimi, Behrooz Mashayekhy
In this paper, we use the theory of simplicial groups to develop the Schur multiplier of a pair of groups to the Baer invariant of it, , with respect to…
A Theorem of Van Kampen Type for Pseudo Peano Continuum Spaces
Hanieh Mirebrahimi, Behrooz Mashayekhy
G. Conner and K. Eda (Topology and its Applications, 146, (2005), 317-328.) introduced a new construction of spaces from groups. They remarked that the construction is not categori…
Topological Homotopy Groups
Helen Ghane, Zainab Hamed, Behrooz Mashayekhy +1
D. K. Biss (Topology and its Applications 124 (2002) 355-371) introduced the topological fundamental group and presented some interesting basic properties of the notion. In this ar…
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…
