Abstract

We investigate some variants of the splitting, reaping, and independence numbers defined using asymptotic density. Specifically, we give a proof of Con($\mathfrak{i}<\mathfrak{s}_{1/2}$), Con($\mathfrak{r}_{1/2}<\mathfrak{b}$) and Con($\mathfrak{i}_*<2^{\aleph_0}$). This answers two questions raised in arXiv:1808.02442v3. Besides, we prove the consistency of $\mathfrak{s}_{1/2}^{\infty} < $ non$(\mathcal{E})$ and cov$(\mathcal{E}) < \mathfrak{r}_{1/2}^{\infty}$, where $\mathcal{E}$ is the $\sigma$-ideal generated by closed sets of measure zero.
