Stability for the inverse resonance problem for the CMV operator    [PDF]

Roman Shterenberg, Rudi Weikard, Maxim Zinchenko

For the class of unitary CMV operators with super-exponentially decaying Verblunsky coefficients we give a new proof of the inverse resonance problem of reconstructing the operator from its resonances - the zeros of the Jost function. We establish a stability result for the inverse resonance problem that shows continuous dependence of the operator coefficients on the location of the resonances.
