On a metric making a $σ$-ideal of subsets of an uncountable Polish space meager

Rok, strany: 1996, 169 - 173

We consider the $σ$-ideal $MGR(F)$ of all sets in a Polish space $X$, which are meager relatively to each set from a countable family $F$ of closed sets, well-ordered by the reverse inclusion. We define a new metric $ρ^*$ on $X$ such that $MGR(F)$ becomes the family of all meager sets with respect to $ρ^*$.
