crated D'Auria-Fre formulation of supergravity
there is a blog entry to go with this here
expanded the section on "rheonomy"
I went through the entry D’Auria-Fre formulation of supergravity and edited a bunch of links, making them point to all the relevant entries on oo-Chern-Weil theory that we have created since the conception of this entry. Also polished up the notation here and there to bring it in line with what is now “standard” in the rest of the Lab.
i reorganized the entry D’Auria-Fre formulation of supergravity a bit in an attempt to polish it. Then I added a section on the “cosmo-cocycle”-condition and how it really defines a Chern-Simons element in the supergravity Lie 6-algebra.
Finally I added a stub section “Examples” where I started writing out the cs-element = Lagrangian for 11d-supergravity, before running out of steam.
I have expanded the Idea section a bit, making the relation to higher Cartan geometry explicit (which is being mentioned in a bunch of nLab entries, but had previously not been added to this relatively old entry itself)
when the $n$Lab is back, the entry D’Auria-Fre formulation of supergravity needs to be added a pointer to
which, while not as detailed as the original Supergravity and Superstrings - A Geometric Perspective, includes discussion of new developments such as AdS/CFT in the special D’Auria-Fre formulation – also it’s still in print.
