Title: σ-ideals invariant under measure-preserving homeomorphisms on Cantor’s cube
Results were obtained together with Taras Banakh and Robert Rałowski. We will show that there are only four nontrivial sigma-ideals with Borel base invariant under measure preserving homeomorphisms on Cantor’s cube. These ideals are: E, M∩N, M, N.
