Extension of bounded Baire-one functions vs Extension of unbounded Baire-one functions
Olena Karlova, Volodymyr Mykhaylyuk
We compare possibilities of extension of bounded and unbounded Baire-one functions from subspaces of topological spaces.
Extension of fragmented Baire-one functions on Lindelöf spaces
Olena Karlova, Volodymyr Mykhaylyuk
We investigate the possibility of extension of fragmented functions from Lindelöf subspaces of completely regular spaces and find necessary and sufficient conditions on a fragmente…
On a problem of Talagrand concerning separately continuous functions
Volodymyr Mykhaylyuk, Roman Pol
We construct a separately continuous function on the product of a Baire space and a zero-dimensional compact space such that no restriction of t…
Extension of Borel maps with values in non-metrizable spaces
Olena Karlova, Volodymyr Mykhaylyuk
We investigate the possibility of extension of -measurable and Baire-one maps from subspaces of topological spaces when these maps take values in spaces which covers by a sequ…
Upper and lower Lebesgue classification of multivalued mappings of two variables
Olena Karlova, Volodymyr Mykhaylyuk
We introduce a functional Lebesgue classification of multivalued mappings and obtain results on upper and lower Lebesgue classifications of multivalued mappings …
Diagonals of separately continuous maps with values in box products
Olena Karlova, Volodymyr Mykhaylyuk
We prove that if is a paracompact connected space and is a product of a family of equiconnected metrizable spaces endowed with the box topology, then for…
