Lebesgue's universal covering problem

ID: lebesgue-s-universal-covering-problem

Lebesgue's universal covering problem is a question in the field of topology, particularly concerning the properties of spaces that can be covered by certain kinds of collections of sets. Specifically, the problem asks whether every bounded measurable set in a Euclidean space can be covered by a countable union of sets of arbitrarily small Lebesgue measure.
