- diffhist Colin de Verdière graph invariant 23:19 −88 Kevin Lamoreau talk contribs (→Characterization of known graph families: I'm not not sure that parenthetical statement is correct; in any case, a single vertex graph might be assumed to not have any loops anyway, so that caveat wouldn't matter)
- diffhist Colin de Verdière graph invariant 23:10 +8 Kevin Lamoreau talk contribs (→Graph minors: making the subscripts of K sub 2 non-italicized)
- diffhist Colin de Verdière graph invariant 23:08 0 Kevin Lamoreau talk contribs (→Graph minors: fixing an error on my last edit (I had copied and pasted and forgotten to change the 'n's to '2's)
- diffhist Colin de Verdière graph invariant 23:06 +265 Kevin Lamoreau talk contribs (→Graph minors: note about how the sole forbidden for a CdV invariant of ≤ 0 (< 1) is {{mvar|{{overline|K}}{{sub|n}}}} rather than {{mvar|K{{sub|n}}}} if it is not assumed that all graphs are connected, as it was in Colin de Verdière's paper)
- diffhist Colin de Verdière graph invariant 22:48 +261 Kevin Lamoreau talk contribs (→Characterization of known graph families: it seems pretty clear from the van der Holst et al paper that K sub 0 would have a CdV invariant of 0 − 1 = −1, and Colin de Verdière's original paper calls K sub 1 a 0-critical graph (he also said K sub 2 was 1-critical, but he wasn't counting non-connected graphs like the compliment of K sub 2); a loop would mean a one-vertex graph is not a linear forest, so the CdV invariant would be ≥ 2)
