Vanilla 1.1.10 is a product of Lussumo. More Information: Documentation, Community Support.
I have added a section Relation to Sullivan models with the statement that the co-binary part of the Sullivan differential equals the $\mathbb{Q}$-linear dual of the Whitehead product.
There is a hidden factor of 2 in that statement, which I would like to understand better. But I’ll give that statement now it’s own entry, and then ask my question there…
finally added the original references
Then I made explicit the subtlety with $[\phi,\phi]_{Wh}$ (here).
Finally I reorganized a little, starting to put the previous material into appropriate subsections.
Thanks for catching this. Both fixed now.
[ The missing re-ordering was a silly typo, but the difference in sign came from thinking L-infinity algebras as opposed to dg-Lie algebras, via the pertinent isomorphism (equation (3) in arXiv:hep-th/9209099). ]
