This is closeely related to the classical notion ot torsors and bundles of modules over an algebra bundle.\n  Twisted K-theory is simply defined as the Grothendieck group of twisted vector bundles (with a given twist). The usual operations on vector bundles (exterior powers, Adams operations) are easily extended to this twisted framework.
