Cardinal Invariants of Analytic $P$ -Ideals

  • Fernando Hernández-Hernández (a1) and Michael Hrušák (a1)

Abstract

We study the cardinal invariants of analytic $P$ -ideals, concentrating on the ideal $Z$ of asymptotic density zero. Among other results we prove $\min \,\{\mathfrak{b},\,\operatorname{cov}(\mathcal{N})\,\}\,\le \,\operatorname{cov}*\,(Z)\,\le \,\max \{\mathfrak{b},\,\text{non(}\mathcal{N}\text{)}\}$ .
