    • started a minimum Idea-section, so far just a stub entry in order to un-gray links in other entries.

      v1, current

    • Removed by admin.

    • Created a stub for this to ’ungrey’some links.

      v1, current

    • Began working on a write up of the material presented in #1 at this nForum post. I will use it as well to experiment with introduction of further Tex style commands (the aim is for the page to compile as-is into LaTex), and to work on relevant nLab pages on knot theory (beginning with link diagram earlier today).

    • went ahead and collected together some links for a combinatorics context side bar.

    • link to wikipedia page on Kuiper.

    • At Chevalley-Eilenberg chain complex the link to Chevalley-Eilenberg cochain complex was grey as was the adjacent link. Initially in the first version by Zoran that link was active. I think that the hyphen was being seen as something else. I changed it back but note that Toby in one of the revisions had made a change to the original. Is it - against – or what? I am bemused! (as usual!)

      BTW the equation giving the differential was very awkwardly formatted, so I changed the formatting a bit.

    • Add the synonym and redirects for J-holomorphic curve.

    • Disambiguation page (recreated from David’s page, which I deleted temporarily).

    • Small improvement to introduction.

    • Making a start on this to collect references.

      v1, current

    • This page appeared in Latest Changes. It’s not in our standard format for named articles. Do we agree it’s a piece of work that merits its own nlab page? If so, we can knock it into shape.

      diff, v5, current

    • Somebody should add a word on categorification to this page (just a note in case anyone cares, maybe a note to myself, but right now I am on my phone…)

    • Minor corrections in the statement and proof of Example 3.1.

      diff, v22, current

    • Added link to book treating the proof, by Haesemeyer and Weibel

    • Observation that the metric topology and product topology agree.

    • I assume nobody still around here still cares much about Rafael Borowiecki’s entry Timeline of category theory and related mathematics?

      I know this entry mostly from when I create new entries: every now and then I think I am creating an entirely un-linked-to new entry, only to see then that the “timeline” is already pointing to it.

      For procrastination purposes I just looked at the entry itfelf for the first time in years. While I still have the opinion that I once voiced there, that more important than making it entirely complete is to remove some (few) weird items, I have to admit it has something to it. Would be a fun thing to look at… if there were fewer broken links in grey.

      But I notice one thing: for a whole bunch of those grey links we actually do have entries. Only the “timeline” does not follow our entry-naming conventions. For instance it asks for a bunch of capitalized keywords which we do have in lower case. It also asks for “Peter Johnstone (mathematician)”, which we don’t have, while of course we do have “Peter Johnstone”, and so on.

      Just in case anyone feels inspired to work on fixing some of these links…

    • stated the actual definition of “universal central extension” (initial object in a category of central extension) and moved the sentence previously offered here (central extensions of perfect groups by via Schur coverings) to the Examples.

    • recorded the realization via G2/SU(3)

      what’s a good survey, if any, of the open question of complex structure on S6?

    • Stub for limit point compactness. To be returned to later.

      v1, current

    • added the statement that symmetric monoidal functors induce functors between categories of commutative monoids (here)

      and

      added the example of the symmetric monoidal equivalence between two symmetric braidings on chain complexes of super vector spaces (here)

    • since this table deserves to be shown in serveral entries, I am giving it a separate entry for !inclusion into other files

    • I’ve added to the formerly stubby long line.

      Incidentally, I thought the one-point compactification of the long line was called the “long circle”, but I don’t see mention of that via google. What’s that thing called?
