    • added briefly something to Ricci flow, amplifying that it is the gradient flow of the action functional of dilaton gravity (equivalently: the renormalization group flow of the string-sigma-model coupled to gravity and dilaton)

    • Fix naming of index variable to match index on expression inside.

    • At the old entry cohomotopy used to be a section on how it may be thought of as a special case of non-abelian cohomology. While I (still) think this is an excellent point to highlight, re-reading this old paragraph now made me feel that it was rather clumsily expressed. Therefore I have rewritten (and shortened) it, now the third paragraph of the Idea-section.

      (We had had long discussion about this entry back in the days, but it must have been before we switched to nForum discussion, because on the nForum there seems to be no trace of it.)

    • I have added in references to Whitehead’s address ’delivered before the Princeton Meeting of the AM Society on November 2, 1946’ that is ‘combinatorial homotopy 1’.

    • am splitting this off as a stand-alone statement (from complex projective space)

      Have cleaned-up the formulation of statement and proof and have generalized from ground ring the complex numbers to reals, complex numbers and quaternions.

    • I thought we had a reference for this on the nnLab, but now I don’t find it:

      What’s a citation for the statement that Groupoids\infty Groupoids is the terminal object in (,1)Toposes(\infty,1)Toposes?

    • a bare table, to be !include-ed under “Related entries” in pertinent entries

      Am trying to bring some order into the mess of entries of cobordism cohomology theories…
