Generic Jumps of Fredholm Indices and the Quantum Hall Effect

Joseph E. Avron, Lorenzo Sadun

Published 2000-03-05Version 1

We describe the generic behavior of Fredholm indices in the space of Toeplitz operators. We relate this behavior to certain conjectures and open problems that arise in the context of the Quantum Hall Effect.
