Title: Universal sets for bases of \(\sigma\)-ideals
Abstract. We shall construct universal sets of possibly low Borel rank for classic \(\sigma\)-ideals of sets: \(\mathcal{N}\)-family of measure zero sets, \(\mathcal{M}\)-family of meager sets, \(\mathcal{M}\cap\mathcal{N}\) and \(\mathcal{E}\). We will also discuss briefly cases of other ideals.
