Abstract
This is the third in a series of works devoted to spectral asymptotics for non-selfadjoint perturbations of selfadjoint -pseudodifferential operators in dimension 2. We assume that the unperturbed operator has a periodic Hamilton flow, and study the remaining generic case; when the flow average of the perturbation has a saddle point
