May 7, 2013 at 21:49 | comment | added | Zhaoting Wei | @shu Thank you very much for your explain! Now I think I get some of the idea: For a family of manifolds $M\rightarrow B$ and a family Dirac operators we have the horizontal and the vertical direction, therefore Quillen's definition of superconnection is necessary to build the suitable operator on $M$. I think you know a lot about this work and hopefully you can write some survey article on it when you have time. | |

Quillen's formalism gives a strategy for the heat kernel proof of the familly index theorem. This strategy is achieved by Bismut later via Bismut supperconnection. | |
May 7, 2013 at 7:29 | comment | added | Willie Wong | Hum... learning something from Quillen does not necessarily imply learning something from reading one of Quillen's papers. It could be that the learning took place in a different setting. Unless the book indicated otherwise, I would not assume that the quote is necessarily referring to any of Quillen's three papers that you indicated. | |
