Robert Rałowski: On m.a.d. s0-nonmeasurable sets with small dominating subfamilies

Tuesday, October 28, 2014, 17:15 Wrocław University of Technology, 215 D-1 Speaker: Robert Rałowski (Wrocław University of Technology) Title: On m.a.d. s0-nonmeasurable sets with a small dominating subfamilies Abstract: We show that d=ℵ1 implies the existence of maximal familiy of eventually different reals on Baire space which forms a nonmeasurable set with respect to an ideals generated by trees (perfect, Laver or Miller trees for example). continue reading…
