| Sep 20, 2023 at 17:40 | comment | added | Christophe Leuridan | The statement of the question is not clear. I suppose that you mean $\mathcal{P}([n]) \setminus \{\emptyset\}$, and that you note $\mathcal{F}_a = \{\mathcal{A} \in \mathcal{F} : \exists B \in \mathcal{A} : \{a\} \in B\}$ for all $a \in [n]$? | |
