Some properties of $\mathcal{I}$-Luzin sets

Abstract

In this paper we consider a notion of I\mathcal{I}-Luzin set which generalizes the classical notion of Luzin set and Sierpi{\'n}ski set on Euclidean spaces. We show that there is a translation invariant σ\sigma-ideal I\mathcal{I} with Borel base for which I\mathcal{I}-Luzin set can be I\mathcal{I}-measurable. If we additionally assume that I\mathcal{I} has Smital property (or its weaker version) then I\mathcal{I}-Luzin sets are I\mathcal{I}-nonmeasurable. We give some constructions of I\mathcal{I}-Luzin sets involving additive structure of Rn\mathbb{R}^n. Moreover, we show that if LL is a Luzin set and SS is a Sierpi{\'n}ski set then the complex sum L+SL+S cannot be a Bernstein set.
