| Apr 23 at 7:00 | comment | added | Dominic van der Zypen | Thanks a lot @bof for this effort! I find statement (4) particularly intriguing. (Obviously one should extend the definition of $\preceq$ to all non-empty subsets of ${\cal P}(X)$, not just covers, because $\{A\}$ intersecting, but usually not a cover.) Also, I will have to think which of the implications between (1),(2),(3) hold in the general setting, not just ${\bf F}$. (Of course some implications are trivial.) | |
