Abstract:
Using a game-theoretic approach (Set-Cover game) we obtain a generalization
of the classical result of Brzuchowski, Cichoń, Grzegorek and
Ryll-Nardzewski on non-measurable unions. We will present applications of
this result to establishing some countability and continuity properties of
measurable functions and homomorphisms between topological groups.
