    Twisted K-theory and representations of loop groups.

    Friday 28th July, 12-1pm, Carslaw 275.

    String theorists have recently revived interest in twisted versions on K-theory which were studied long ago by Karoubi, Donovan, and others. A striking application of a pure mathematical nature which has been discovered recently by Freed, Hopkins, and Teleman is to describe the representation ring of a loop group as the twisted equivariant K-theory of a space.
