I added a discussion of space in Kant’s Transcendental Aesthetics in Critique of Pure Reason.
By the way, the translation of the quote from Kant in the section “On Aristotelian logic” seem a bit strange: I think the original German sentence was “Begriffe aber beziehen sich als Prädikate möglicher Urtheile auf irgend einen noch unbestimmten Gegenstand” (“But conceptions, as predicates of possible judgements, relate to some representation of a yet undetermined object.”).
PS The automatic function to create this thread in the nforum did not word.

splitting this off from Schwinger effect, to go with a list of entries on fundamental scales

I created the page
with some discussion and references on the various triangulated categories associated to a scheme (e.g. bounded derived category of coherent sheaves, triangulated category of perfect complexes).

stub – for the moment just so as to satisfy links at Schwinger effect
a few more details at model structure for left fibrations
added pointer to Figueroa-O’Farrill 98 (which will be my choice of canonical reference, unless a better one surfaces…)
I have split morphism of sites off from site, and in the process made bold to change the definition to the one I think is inarguably correct, using covering-flatness rather than representable-flatness (which is equivalent in case the sites have finite limits and subcanonical topologies). I made corresponding changes to the statements of the theorems relating morphisms of sites to geometric morphisms, but I don’t have the time or energy to change the proofs, so I left them as-is with pointers to my paper for proofs in the general case. It would be nice to have proofs of these theorems in the general case that don’t require the reader to understand -ary exact completion for general , but I can’t think when I might have time to write out such proofs in the foreseeable future myself.

cross-linked with Euler form and added these pointers:
Discussion of Euler forms (differential form-representatives of Euler classes in de Rham cohomology) as Pfaffians of curvature forms:

am finally splitting this off as a stand-alone page (material used to be at cosmological constant and at F-theory). Added a paragraph linking with inhomogeneous cosmology.
some minimum, in order to go along with the recent addition to Witten’s Dark Fantasy.
