Martin DOLEZAL: Haar meager sets

-----
Abstract: The notion of Haar meager sets in abelian Polish groups was introduced by Darji. Haar meager sets form a topological counterpart to Haar null sets defined by Christensen. We 
show some analogies of Haar meager sets and Haar null sets. On the other hand, we show that some Polish groups can be decomposed into a Haar meager and a Haar null set.
