| Mar 19, 2021 at 20:27 | comment | added | Johannes Schürz | This paper deals with your first question question.Your second question seems trickier, because using Hechler forcing in the template construction will likely yield $\text{add}(\mathcal{M})=\text{cof}(\mathcal{M})$. | |

| Mar 19, 2021 at 13:22 | comment | added | Will Brian | Shelah proved the consistency of both $\mathfrak{d} < \mathfrak{a}$ and the consistency $\mathfrak{u} < \mathfrak{a}$. (Same paper, but two different models.) I would not be surprised if one of these models had $\mathrm{non}(\mathcal M) < \mathfrak{a}$ as well. If no one is able to answer your question outright, you might want to try computing $\mathrm{non}(\mathcal M)$ in these models, or try to modify the techniques from that paper. | |
