K. Pankrashkin, S. Richard Spectral and scattering theory for the Aharonov-Bohm operators (346K, pdf) ABSTRACT. We review the spectral and the scattering theory for the Aharonov-Bohm model on R^2. New formulae for the wave operators and for the scattering operator are presented. The asymptotics at high and at low energy of the scattering operator are computed.
