COMPLETE NONMEASURABILITY IN REGULAR FAMILIES

open access: yes, 2014
. We show that for a σ-ideal I with a Borel base of subsets of an uncountable Polish space, if A is (in several senses) a ”regular ” family of subsets from I then there is a subfamily of A whose union is completely nonmeasurable i.e.
