On the Selection of Compact Subsets of Positive Measure from Analytic Sets of Positive Measure
An important but seemingly difficult problem is to decide whether or not an analytic set A of positive h -measure, for some continuous Hausdorff function h , contains a compact subset C of positive h -measure, in every complete separable metric space Ω. By extending some earlier work of R. …
