Abstract:
We show that if every set of reals of size ${2^{{\aleph _0}}}$ contains a meager-to-one continuous image of a set that cannot be covered by less than ${2^{{\aleph _0}}}$ meager sets, then there exists a null (Lebesgue measure zero) subset of the plane $\mathbb {R} \times \mathbb {R}$ that meets every nonnull rectangle $X \times Y$. The antecedent is satisfied, e.g., if ${\omega _2}$ Cohen reals are added to a model of the continuum hypothesis.References
