twisted equivariant differential K-theory

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 the D-brane charge quantization in topological K-theory conjectured to apply to non-perturbative type II string theory.

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:
