| Nov 22, 2019 at 17:54 | comment | added | Yemon Choi | @SamHopkins Thanks - this is almost the same although note that my construction allows the empty set to belong to ${\mathcal F}\wedge\Gamma$. Moreover, since in that language I want to delete some vertices and then remove some hyperedges, I seem to have a sub-subhypergraph where the first sub doesn't mean the same as the second sub ... :-/ | |
