*Copenhagen Meeting on Differential Characters*

#### Posted by Urs Schreiber

Am in Denmark on vacation. And for attending a day or two of the

Copenhagen meeting on differential characters.

*Differential characters* are one model for what *Deligne cohomology* and *abelian $n$-gerbes with connection* are other models for: the differential cohomology refinement of the ordinary Eilenberg-MacLane cohomology theory $K(-,\mathbb{Z})$.

Myself, I’ll talk about this:

$\infty$-topos theoretic differential characters and the $\infty$-Chern-Weil homomorphism on principal $\infty$-bundles.
