Borel complexity of sets of ideal limit points

Rafal Filipow, Adam Kwela, Paolo Leonetti

Let $X$ be an uncountable Polish space and let $I$ be an ideal on $ω$ . A point $η \in X$ is an $I$ -limit point of a sequence $(x_{n})$ taking values in $X$ if ther…

Topological complexity of ideal limit points

Marek Balcerzak, Szymon Glab, Paolo Leonetti

Given an ideal $I$ on the nonnegative integers $ω$ and a Polish space $X$ , let $L (I)$ be the family of subsets $S \subseteq X$ such that $S$ is the set…
