    • Just what it says in the title. The list of differences is not yet complete.

    • Created page, copying material from the one on David Roberts’ web.

    • added pointer to today’s

      • Joás Venâncio, Carlos Batista, Two-Component Spinorial Formalism using Quaternions for Six-dimensional Spacetimes (arXiv:2007.04296)

    • to go with David C.’s recent edits

      v1, current

    • I have added some things to frame. Mostly duplicating things said elsewhere (at locale and at (0,1)-topos), but I need these statements to be at frame itself.

    • started a bare minimum at Poisson-Lie T-duality, for the moment just so as to have a place to record the two original references

    • discovered this old but empty entry. Made it point to CR-manifold

      (it might just be cleared and “CR-structure” made a redirect for “CR-manifold”)

      diff, v2, current

    • I have added to algebra for an endofunctor a remark on the relation to algebras over free monads. While I think that’s pretty obvious, I notice that a) recently somebody has blogged about that here, b) here it says that it’s not true :-) (but I think it’s not meant to be read that way).

    • added pointer to

      • Maks A. Akivis, Vladislav V. Goldberg, Conformal and Grassmann structures, Differential Geom. Appl. 8 (1998) no. 2 177-203 (arXiv:math/9805107)

      for discussion of conformal structure as G-structure

    • Removed link from Eric Forgy that was placed by one TessWither. There was a little bit of other activity around that seemed to be just minor edits to create a smokescreen.

    • Hello,

      I noticed DFT page has not been updated in a while and I added a couple of sections: some sketchy introductory material (analogy between Kaluza-Klein and DFT) and a little insight about a more rigorous geometrical formulation of DFT.

      It is still quite sketchy but I would be happy to refine it.

      PS: this is my first edit, I hope I played by the rules. And thank you all for this wiki

    • I added a comment on the Calabi-Yau variety page about c 1=0c_1=0. Does anyone know if it’s still true in the non-compact case?

      Also, what’s the proper way to add questions/parenthetical remarks to n-Lab pages?

    • I want this entry to have an actual section on construction of (compact) Examples, so I started one (here). But so far there is nothing in there apart from pointers to the original articles by Joyce and Kovalev, and a graphics illustrating Kovalev’s twisted connected sums.

      diff, v51, current

    • I’ve created a page for quaternionic manifolds, linked from quaternion-Kähler page. Basic references and discussion of main definition re Cauchy-Feuter calculus. Comparison to hypercomplex structure.
