Effective codescent morphisms of Hausdorff topological spaces
Dali Zangurashvili
Our earlier results on effective codescent morphisms of Hausdorff topological spaces are strengthened and complemented. In particular, it is proved that any embedding $p:B\rightarr…

The free product of topological groups being Hausdorff is Hausdorff --- a new proof
G. Samsonadze, D. Zangurashvili
The explicit description of the topology of the free product of topological groups being Hausdorff is given. In particular, it is shown that it coincides with the so-called -t…

Amalgamated free products of topological groups being Hausdorff -- a new approach
Guram Samsonadze, Dali Zangurashvili
The paper deals with the problem posed by Katz and Morris whether the free product with amalgamation of any Hausdorff topological groups is Hausdorff, the negative solution of whic…
