### Notes on Differential Nonabelian Cohomology

#### Posted by Urs Schreiber

I have begun to prepare on my personal $n$Lab page notes on stuff that I am working on. Some of it is in a state that should be readable and on which I would enjoy getting comments. This I want to present here.

The entry point for the technical material is here:

- $n$Lab/schreiber/differential nonabelian cohomology

Behind the above link you find pointers to more information.

So far the material available there concerns the abstract definition of differential cohomology in an arbitrary $(\infty,1)$-topos and the derivation from that of the notion of $\infty$-Cartan-Ehresmann connection on principal $\infty$-bundles.
