Ideals with Smital properties

General Topology 2021-12-14 v2

Abstract

A σ\sigma-ideal I\mathcal{I} on a Polish group (X,+)(X,+) has Smital Property if for every dense set DD and a Borel I\mathcal{I}-positive set BB the algebraic sum D+BD+B is a complement of a set from I\mathcal{I}. We consider several variants of this property and study their connections with countable chain condition, maximality and how well they are preserved via Fubini products.
