On the Alexandroff-Borsuk problem
Matija Cencelj, Umed H. Karimov, Dušan D. Repovš
We investigate the classical Alexandroff-Borsuk problem in the category of non-triangulable manifolds: Given an -dimensional compact non-triangulable manifold and $\vareps…
On nerves of fine coverings of acyclic spaces
Umed H. Karimov, Dušan D. Repovš
The main results of this paper are: (1) If a space can be embedded as a cellular subspace of then admits arbitrary fine open coverings whose nerves are homeo…
On Snake cones, Alternating cones and related constructions
Katsuya Eda, Umed H. Karimov, Dušan Repovš +1
We show that the Snake on a square is homotopy equivalent to the space which was investigated in the previous work by Eda, Karimov and Repov\vs. We also introdu…
On 2-dimensional nonaspherical cell-like Peano continua: A simplified approach
Katsuya Eda, Umed H. Karimov, Dušan Repovš
We construct a functor from the category of path connected spaces with a base point to the category of simply connected spaces. The following are the main results…
On generalized 3-manifolds which are not homologically locally connected
Umed H. Karimov, Dušan Repovš
We show that the classical example of a 3-dimensional generalized manifold constructed by van Kampen is another example of not homologically locally connected (i.e. not HLC) sp…
On the homology of the Harmonic Archipelago
Umed H. Karimov, Dušan Repovš
We calculate the singular homology and Čech cohomology groups of the Harmonic archipelago. As a corollary, we prove that this space is not homotopy equivalent to the Griffiths spac…
A construction of noncontractible simply connected cell-like two dimensional Peano continua
Katsuya Eda, Umed H. Karimov, Dušan Repovš
Using the topologist sine curve we present a new functorial construction of cone-like spaces, starting in the category of all path-connected topological spaces with a base point an…
