"We show that point-countable F-sigma-delta-additive family of subsets of an absolutely Suslin space is sigma-discretely refinable. This generalizes a theorem of R.W. Hansell. We apply this result on the existence of Borel measurable selectors for multivalued mappings of low Borel complexity, answering thus affirmatively a particular version of a question of J. Kaniewski and R. Pol."@en . . "We show that point-countable F-sigma-delta-additive family of subsets of an absolutely Suslin space is sigma-discretely refinable. This generalizes a theorem of R.W.
