Title: Commutators methods for magnetic Schroeodinger operators

Abstract: We analyze the spectral properties associated to some
magnetic Schroedinger equations, subject to periodic time dependent
perturbations, in dimensions n = 2 and n = 3. To this end, we use a
unitary version of the Mourre commutator estimates to obtain, for
example, the absence of singular continuous spectrum of the
corresponding Floquet operator.
