Vanilla 1.1.10 is a product of Lussumo. More Information: Documentation, Community Support.
Stub context-free grammar.
it is long overdue that we create a table listing what appears in the ADE pattern.
In a stolen minute I gave it a start at ADE – table.
brief category:people
-entry for hyperlinking references at gauge-Higgs unification and at Higgs field, GUT and elsewhere
stub, just to fill an entry in low dimensional rotation groups – table

I have created a minimum at global family (a suitable family of groups in the sense of global equivariant homotopy theory).
Hm, the set of finite subgroups of or of . Is that a global family? I.e. is it closed under quotient groups by normal subgroups?
I made “classification of simple Lie groups” a redirect to this entry, and added a graphics showing the Dynkin diagram correspondence (added that also to Dynkin diagram)
but somebody should really start an entry of that title and do it some justice
started a stub, to satisfy links at Dwyer-Wilkerson space
Mike added two new relevant links to WISC.
I added a section about internal WISC, and changed what was about ’internal WISC’ to ’external WISC in other categories’.
Over at Monster group, I wrote out a description via a group presentation. Of course, it makes no pretense to be illuminating (although it is well-known to experts like Conway; it’s probably in his book with Sloane on the Leech lattice and sphere packings).
Some stuff at Mathieu group, including the fact there are several of them and references to the binary Golay code, of which the largest Mathieu group is the automorphism group.
stub for type II geometry
brief category:people
-entry for hyperlinking references at homotopy Lie group
thought we need such an entry; started something, so far with cross-links to Riemann hypothesis, volume conjecture and image of beta
I have turned logos from a redirect to Heyting category into a stand-alone disambiguation entry, to account for Joyal’s proposal from 2008 (maybe meanwhile abandoned?) to say “logos” for “quasi-category”.
brief category:people
-entry for hyperlinking references at cohomotopy and at equivariant Tietze extension theorem
Made a start on this at orthogonal subcategory problem. There should be much more to say about this with regard to various generalities in model category theory. Needs some clean-up. Please have a look.
stub for toric variety
Stub Makkai duality, just recording the most basic references so far; linked from Stone duality.
Added Makkai duality as related.
at surjective geometric morphism I have spelled out in detail most of the proof of the various equivalent characterizations, and all of the proof of the statement that geometric surjections are comonadic.
created coherent topological space. Just the definition so far.
statement of the 3x3 lemma
