Stability of the Marchenko inversion. (English) Zbl 0641.35070

The stability of the Marchenko inversion in the one-dimensional non- relativistic quantum mechanics is studied. First, two bounds on the integral of the potential difference are given in terms of the integral of the difference in the scattering matrix. Second, a pointwise bound on the potential difference is obtained. Finally, the estimates are refined for the case of two scattering matrices coinciding on the finite energy interval \(k\in [0,N]\).
