Topological aspects of generalized Harper operators    [PDF]

Giuseppe De Nittis, Giovanni Landi

A generalized version of the TKNN-equations computing Hall conductances for
generalized Dirac-like Harper operators is derived. Geometrically these
equations relate Chern numbers of suitable (dual) bundles naturally associated
to spectral projections of the operators.
