### Context

#### $\infty$-Chern-Weil theory

#### Differential cohomology

**differential cohomology**

## Ingredients

## Connections on bundles

## Higher abelian differential cohomology

## Higher nonabelian differential cohomology

## Fiber integration

## Application to gauge theory

## Idea

A connection of a bundle 2-gerbe is essentially a Cech-realization of a degree 4-cocycle in Deligne cohomology.
