## Idea

The notion of twisted equivariant differential K-theory is meant to be the joint generalization of all three variations of topological K-theory given by

hence the joint generalization of

It is this joint generalization that is, ultimately, required by

1. conjectured to apply to non-perturbative type II string theory;

2. conjectured to apply in topological condensed matter theory.

## References

The construction of full twisted & equivariant & differential cohomology theories had long been left open. It does follow as an immediate consequence of the twisted & equivariant Chern-Dold character and as such is discussed in:

The twisted + equivariant + flat differential sector of K-theory is more readily described:
