On the cardinal characteristics associated with \varepsilon

03.05.2022 15:00 - 16:30

M. A. Cardona Montoya (TU Wien)

Let \(\varepsilon\) be the \(\sigma\)-ideal generated by closed measure zero sets of reals. We prove that, for \(\varepsilon\), their associated cardinal characteristics (i.e. additivity, covering, uniformity and cofinality) are pairwise different.
