Room: D1-215
Speaker: Marcin Michalski
Title: Luzin's theorem
Abstract. In 1934 Nicolai Luzin proved that each subset of the real line can be decomposed into two full subsets with respect to ideal of measure or category. We shall present the proof of this result partially decoding his work and we will also briefly discuss possible generalizations.

Title: Indescructible tower
Abstract. Following the Kunen's construction of m.a.d. family which is indestructible over adding \(\omega_2\) Cohen reals we provide analogous construction for indestructibe tower.
