    • As an outcome of recent discussion at Math Overflow here, Mike Shulman suggested some nLab pages where comparisons of different definitions of compactness are rigorously established. I have created one such page: compactness and stable closure. (The importance and significance of the stable closure condition should be brought out better.)

    • am starting some minimum here. Have been trying to read up on this topic. This will likely become huge towards beginning of next year

      v1, current

    • Added a reference

      • John Rognes, Galois extensions of structured ring spectra/Stably dualizable groups, Memoires of the American Mathematical Society, 192(898), 2008, partly available as (pdf)

      diff, v11, current

    • Corrected the spelling.

      In English, “étale” in “étale space” is definitely an adjective, not a past participle (otherwise it would be “étaled space”).

      The last “e” is always silent in the English pronunciation, so cannot be an “é”.

      This also matches the usage in the literature.

    • Mention the Yoneda embedding/free cocompletion which was somehow not referenced before.

      diff, v13, current

    • Just created a stub to be filled in, to make sure that the page is able to be created.

    • brief category:people-entry for hyperlinking references

    • Page created, but author did not leave any comments.

    • Edit to: GUT by Urs Schreiber at 2018-04-01 01:21:13 UTC.

      Author comments:

      added pointer to textbook account

    • Create page with some initial contents.

      v1, current

    • added pointer to these two recent references, identifying further L L_\infty-algebra structure in Feynman amplitudes/S-matrices of perturbative quantum field theory:

    • starting something – not done yet

      v1, current

    • a stub, just so as to make the link work

      v1, current

    • Updated Jim’s (non)-affiliation. He was attached to UCR (clearly) and Macquarie. Anywhere else that should be added? I think more links to other pages could be added, and certainly the ones I’ve now added could have commentary around them. For instance, the list of neologisms that Jim had added deserve a section of their own, I think. But no time now.

      diff, v12, current

    • just a stub for the moment, in order to make links work
