Abstract

In the present paper complete wave operators are constructed in the framework of nonselfadjoint Kato model for a wide class of not necessarily small relatively smooth perturbations. For one-dimensional Schröedinger operator with complex potential possessing finite first momentum a criterion of similarity to a selfadjoint operator is obtained which extends and supplements Kato sufficient condition.
