SWhat changed
Proved finite equidecomposition of bounded subsets with interior in dimensions at least three.
Scientific scope
The record is the exact two-author 1924 French paper. It concerns nonmeasurable set-theoretic pieces, not a physically executable cutting process, and does not absorb Hausdorff’s antecedent or later refinements concerning choice principles and piece counts.
