Two undecidable questions about group actions

Research output: Contribution to journalArticlepeer-review

Abstract

It is shown that for invariance under the action of special groups the statements “Every invariant PCA is decomposable into ℵ1 invariant Borel sets” and “Every pair of invariant PCA is reducible by a pair of invariant PCA sets” are independent of the axioms of set theory.
