Clifford modules and twisted K-theory, by Max Karoubi

The purpose of this short paper is to make the link between the fundamental work of Atiyah, Bott and Shapiro MR0167985 (29/5250) and twisted K-theory MR0282363 (43/8075). This link was implicit in the literature (for real vector bundles overs spheres for instance) but was not been explicitly defined before.
