Approximation of continuous functions on Fréchet spaces
M. A. Mytrofanov, A. V. Ravsky
We consider approximations of a continuous function on a countable normed Fréchet space by analytic and -analytic. Also we found a criterium of the existence of an extension of…
On cake dividing

We consider Steinhaus cake dividing game.
On H-closed paratopological groups
Alex Ravsky
A Hausdorff paratopological group G is H-closed if G is closed in each Hausdorff paratopological group containing G. We obtain criteria of H-closedness for some classes of abelian…
The regularity of quotient paratopological groups
Taras Banakh, Alex Ravsky
Let be a closed subgroup of a regular abelian paratopological group . The group reflexion of is the group endowed with the strongest group topology, weaker…
On feebly compact paratopological groups
Taras Banakh, Alex Ravsky
We obtain many results and solve some problems about feebly compact paratopological groups. We obtain necessary and sufficient conditions for such a group to be topological. One of…
