Twisted K-theory and cohomology
Michael Atiyah, Graeme Segal
We explore the relations of twisted K-theory to twisted and untwisted classical cohomology. We construct an Atiyah-Hirzebruch spectral sequence, and describe its differentials rati…
Twisted -theory
Michael Atiyah, Graeme Segal
Twisted complex -theory can be defined for a space equipped with a bundle of complex projective spaces, or, equivalently, with a bundle of C-algebras. Up to equivalence,…
A Variant of K-theory: K_{+-}
Michael Atiyah, Michael Hopkins
We describe a variant of K-theory for spaces with involution, built from vector bundles which are sent to their negative under the involution.

A brief account of K-theory written in honour of Friedrich Hirzebruch
