Comment.Math.Univ.Carolin. 56,1 (2015) 45-50.

Abstract:We give a classical proof of the theorem stating that the $\sigma $-ideal of meager sets is the unique $\sigma $-ideal on a Polish group, generated by closed sets which is invariant under translations and ergodic.

Keywords: Polish group; $\sigma $-ideal; meager sets
