Abstract

In this paper we consider Schrödinger operators on noncompact star-shaped graphs including some finite rays. We show that our spectral representation formula provides the time dependent formulation of the scattering theory. The scattering operator S is constructed in the configuration space, and then is related to the scattering matrix S(λ) in the momentum space. Corresponding inverse scattering problem is investigated.
