Twisted K-theory and loop groups
Daniel S. Freed
Twisted K-theory has received much attention recently in both mathematics and physics. We describe some models of twisted K-theory, both topological and geometric. Then we state a…

K-Theory in Quantum Field Theory
Daniel S. Freed
We survey three different ways in which K-theory in all its forms enters quantum field theory. In Part 1 we give a general argument which relates topological field theory in codime…
