Abstract

In recent works we considered an asymptotic problem for orthogonal polynomials when a Szeg\"o measure on the unit circumference is perturbed by an arbitrary Blaschke sequence of point masses outside the unit disk. In the current work we consider a similar problem in the scattering setting.
