Title: On generalized Luzin sets

Abstract:

We will show results obtained together with Sz. Żeberski concerning properties of (I,J)-Luzin sets (for I, J sigma-ideals on Polish space). Under some settheoretical assumptions we will construct continuum many generalized Luzin sets which are not Borel equivalent. We will also examine some forcing notions which do not kill generalized Luzin sets.
