Families index theorem in supersymmetric WZW model and twisted Ktheory
Abstract
The construction of twisted Ktheory classes on a compact Lie group is reviewed using the supersymmetric WessZuminoWitten model on a cylinder. The Quillen superconnection is introduced for a family of supercharges and the Chern character for the family is given and its relation to twisted cohomology is discussed.
