The aim of this article is twofold:1. we give a quick introduction to twisted K-theory and, more generally, twisted homology and cohomology theories from a homotopy theoretic point of view, and2. we construct a twisted version of Segal’s connective K-homology theory.The first half of this article is based on talks delivered by the author during the conference “Noncommutative Geometry and Physics 2008–K-theory and D-brane–”. The basic idea of twisting generalized cohomology theories already appeared in the paper [AS04] by Atiyah and Segal, in which a modern treatment of twisted K-theory was introduced. Their construction is based on a homotopy theoretic point of view, ie as cohomology theories twisted by automorphisms of representing spectra. Nowadays algebraic topologists regard twisted (co) homology theories as (co) homology theories defined by bundles of spectra. See, for example, CL Douglas [Dou06]. A more systematic study was done by Waldmüller in [Wal]. The first half of this article is intended to be an exposition of basic ideas behind these abstract approaches to twisted (co) homology theories for those who are not familiar with homotopy theory.
