On the Capacity and Depth of Compact Surfaces
Mahboubeh Abbasi, Behrooz Mashayekhy
K. Borsuk in 1979, in the Topological Conference in Moscow, introduced the concept of capacity and depth of a compactum. In this paper, we compute the capacity and depth of compact…
The Capacity of Wedge Sum of Spheres of Different Dimensions
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 and raised some interesting questions about it. In this paper, dur…

K. Borsuk in 1979, in the Topological Conference in Moscow, introduced the concept of the capacity of a compactum and asked some questions concerning properties of the capacity of…
On Semicovering, Subsemicovering and Subcovering Maps
Majid Kowkabi, Behrooz Mashayekhy, Hamid Torabi
In this paper, by reviewing the concept of subcovering and semicovering maps, we extend the notion of subcovering map to subsemicovering map. We present some necessary or sufficien…
Topological Coarse Shape Homotopy Groups
Fateme Ghanei, Hanieh Mirebrahimi, Behrooz Mashayekhy +1
Uchillo-Ibanez et al. introduced a topology on the sets of shape morphisms between arbitrary topological spaces in 1999. In this paper, applying a similar idea, we introduce a topo…
On Relative Central Extensions and Covering Pairs
Azam Pourmirzaei, Mitra Hassanzadeh, Behrooz Mashayekhy
Let be a pair of groups. In this article, first we construct a relative central extension for the pair such that special types of covering pair of are homom…
