Abstract:

The paper is concerned with a recent very interesting theorem obtained by Holický and Zelený. We provide an alternative proof avoiding games used by Holický and Zelený and give some generalizations to the case of set-valued mappings.

Keywords: Borel maps; sigma-compact sections; set-valued maps
