On Exact Sequences of the Rigid Fibrations
Tayyebe Nasri, Behrooz Mashayekhy
In 2002, Biss investigated on a kind of fibration which is called rigid covering fibration (we rename it by rigid fibration) with properties similar to covering spaces. In this pap…
On Strong Small Loop Transfer Spaces Relative to Subgroups of Fundamental Groups
S. Z. Pashaei, B. Mashayekhy, M. Abdullahi Rashid
Let be a subgroup of the fundamental group . By extending the concept of strong SLT space to a relative version with respect to , strong -SLT space, first…
The Capacity of Some Classes of Polyhedra
Mojtaba Mohareri, Behrooz Mashayekhy, Hanieh Mirebrahimi
K. Borsuk in 1979, in the Topological Conference in Moscow, introduced the concept of the capacity of a compactum. In this paper, we compute the capacity of the product of two sphe…
On Topologized Fundamental Groups with Small Loop Transfer Viewpoints
Noorollah Jamali, Behrooz Mashayekhy, Hamid Torabi +2
In this paper, by introducing some kind of small loop transfer spaces at a point, we study the behavior of topologized fundamental groups with the compact-open topology and the whi…

The paper is devoted to study the th Hawaiian group , , of the wedge sum of two spaces . Indeed, we are going to gi…
Adjointness of Suspension and Shape Path Functors
Tayyebe Nasri, Behrooz Mashayekhy, Hanieh Mirebrahimi
In this paper, we introduce a subcategory of Sh and obtain some results in this subcategory. First we show that there is a natural bijection $Sh (Σ(X, x), (Y…
