quick addition of "formal infinitesimal spaces" and Weil algebras to infinitesimal space

but am planning to polish this entry further later, it is a bit of a mess at the moment

started integration axiom, but incomplete for the moment

at schreiber:integration of oo-Lie algebroid valued differential forms I am thinking about the higher version of this

Looks like maybe Todd is right at cyclic order that the cycle category cannot be defined in that way.

Just learnt about detexify from the Secret Blogging Seminar and thought it worth adding to the online resources page.

A little more detail at natural isomorphism, including when one can speak of the functor satisfying certain conditions.

By chance I came across an old CatTheory mailing list post by e. Dubuc, where he complains about how is work on SDG is not sufficiently recognized and asks people to speak of the "Dubuc topos".

I added a remark about this to synthetic differential geometry in the section on "Well adapted models".

A few more sections at A Survey of Elliptic Cohomology - elliptic curves on

topol. invariants of the moduli stack of ell. curves

the compactified version

the definition of Gromov-Witten invariants

an example.

As before, this is raw material which I am thinking lends itself to be turned into entries.

not much there, yet, but these pages serve a purpose as listing the pages that link to them, which is useful I think

A list of all recently edited entries can be seen at Recently Revised. But that list tends to contain lots of minor changes: it's not easy to spot the important ones. So, if you feel people's attention should be drawn to some changes you make, then please mention them

*here*. This way the rest of us can spot them, so we can learn what you know — and maybe make further improvements!- Go to the Latest Changes category in the Forum. If you are reading this on the forum, then you are there right now, or go to http://www.math.ntnu.no/~stacey/Vanilla/nForum/?CategoryID=5.
- Optionally, create an account (if you don't have one) and log in if necessary; this may be helpful but is not required.
- Hit ‘Start new discussion’ at the upper left.
- Choose a meaningful subject title, perhaps the name of the page you've edited or something like that.
- Write a brief message summarising your edit. Most of the formatting is the same as on the Lab if you choose the ‘Markdown+Itex’ radio button beneath the comment box.
- Please include a
