    • added pointer, here and in related entries, to

      being one of the early references considering the computation of black hole radiation in terms of thermal field theory on Wick-rotated spacetimes with compact/periodic “Euclidean time”.

      diff, v22, current

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

      v1, current

    • stub entry for the moment, to satisfy links

      v1, current

    • Definition of extensional PiPi-type structure taken from Natural models of homotopy type theory

      Should we develop how to get application, β\beta and η\eta here or should we leave it to the interpretation ?

      v1, current

    • Created categorical model of dependent types, describing the various different ways to strictify category theory to match type theory and their interrelatedness. I wasn’t sure what to name this page — or even whether it should be part of some other page — but I like having all these closely related structures described in the same place.

    • I fixed a broken link to Guy Moore’s lectures

      diff, v9, current

    • Added missing axiom. To see that an axiom like that is necessary, just observe that in the former formulation (without the first assumption) the requirements for meet and join were symmetric.

      diff, v25, current

    • added pointer to

      • R. P. Brent, J. van de Lune, H. J. J. te Riele and D. T. Winter, On the Zeros of the Riemann Zeta Function in the Critical Strip. II, Mathematics of Computation Mathematics of Computation Vol. 39, No. 160 (Oct., 1982), pp. 681-688 (doi:10.2307/2007345 )

      for computer-checks of the Riemann hypothesis. (there are probably more recent such?)

      diff, v8, current

    • Created semi-simplicial set, mainly as a repository for some terminological remarks. I would welcome anyone more knowledgeable about the history to correct or improve it!

    • Added some remark on the order of a semiring. Actually, does anybody know if any semiring embedds into a semifield?

      diff, v5, current

    • some minimum, see the related edit announcement here

      v1, current

    • added a little bit more text and pointers, to make this entry a little less stubby

      diff, v5, current

    • created computational trinitarianism, combining a pointer to an exposition by Bon Harper (thanks to David Corfield) with my table logic/category-theory/type-theory.

    • Move to full name; correct relationship to tangent.

    • I do not understand the entry G-structure. G-structure is, as usual, defined there as the principal GG-subbundle of the frame bundle which is a GL(n)GL(n)-principal bundle. I guess this makes sense for equivariant injections along any Lie group homomorphism GGL(n)G\to GL(n). The entry says something about spin structure, warning that the group Spin(n)Spin(n) is not a subgroup of GL(n)GL(n). So what is meant ? The total space of a subbundle is a subspace at least. Does this mean that I consider the frame bundle first as a (non-principal) Spin(n)Spin(n)-bundle by pulling back along a fixed noninjective map Spin(n)GL(n)Spin(n)\to GL(n) and then I restrict to a chosen subspace on which the induced action of Spin group is principal ?

    • slightly expanded the Idea-section. But the entry remains a stub

    • I was thinking/hoping now that a general approach to perturbative QFT should exist, where all Feynman amplitudes are regarded not as singular distributions on M nM^n, but as smooth differential forms on the FM-compactification of the configuration space of nn points. Mentioning this hunch to Igor Khavkine, he immediately recalled having heard Marko Berghoff speak about developing just that in his thesis Berghoff 14.

    • keep needing to point to this, so I finally gave it its own entry
