Abstract

A discrete model of the integer quantum Hall effect is analysed via its associated C*-algebra. The relationship with the usual continuous models is established by viewing the observable algebras of each as both twisted group C*-algebras and twisted cross products. A Fredholm module for the discrete model is presented, and its Chern character is calculated.
