    • Stub with reference and basic quotes

    • added to G2 the definition of G 2G_2 as the subgroup of GL(7)GL(7) that preserves the associative 3-form.

    • am starting a stub, for the moment just so as to have a place to record some references

    • some minimum, for the moment just so as to make links work

    • am giving this group its own entry, so that every entry using it (such as quaternion-Kähler manifold) makes sure that the notation is not being confused with the direct product group.

      What’s the source of this notation?

    • At Fréchet space I have added to the Idea-section a paragraph motivating the definition via families of seminorms from the example of =lim n n\mathbb{R}^\infty = \underset{\longleftarrow}{\lim}_n \mathbb{R}^n. And I touched the description of this example in the main text, now here.

    • corrected spelling of “transcribed” in point 2 following Def. 2.1

    • I am splitting off an entry classification of finite rotation groups from ADE classification in order to collect statements and references specific to the classification of finite subgroups of SO(3)SO(3) and SU(2)SU(2).

      Is there a canonical reference for the proof of the classification statement? I find lots of lecture notes that give the proof, but all of them without citing sources or original publications of proofs.

    • added in CW-complex in the Examples section something about noncompact smooth manifolds.

      Eventually it would be good to state here precisely Milnor’s theorem etc. Googling around I seem to see a lot of misleading imprecision in the usual statements along these lines (on Wikipedia and MO) concerning the distinctions between countably generated and general CW-complexes and concerning homotopy equivalence vs weak homotopy equivalence.

    • Added some references to sheaf-theoretic interpretations of choice sequences

      diff, v2, current

    • Created page to record statements and the relation between them.
