The null ideal restricted to some non-null set may be $\aleph

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/150721Our main result is that possibly some non-null set of reals cannot be divided to uncountably many non-null sets. We deal also with a non-null set of reals, the graph of any function from it is null and deal with our iterations somewhat more generally.LogicThe null ideal restricted to some non-null set may be $\aleph_1$-saturatedtext
