Banach and Tarski: decomposition of point sets into congruent parts

Established finite equidecomposition results in Euclidean spaces of dimension at least three, including the result now known as the Banach–Tarski paradox under the set-theoretic assumptions used.

What is recorded here?

Established finite equidecomposition results in Euclidean spaces of dimension at least three, including the result now known as the Banach–Tarski paradox under the set-theoretic assumptions used.

Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.

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.

Read the original work

This English explanation is an editorial reading view. It does not replace the complete original work or certify its science.
