The Atiyah–Segal completion theorem in twisted K–theory

A basic result in equivariant $K$ –theory, the Atiyah–Segal completion theorem relates the $G$ –equivariant $K$ –theory of a finite $G$ –CW complex to the non-equivariant $K$ –theory of its Borel construction. We prove the analogous result for twisted equivariant $K$ –theory.
