Abstract

We give an exposition on the L2 theory of the perturbed Fourier transform associated with a Schrödinger operator H=−d2∕dx2+V on the real line, where V is a real-valued finite measure. In the case V L1∩L2, we explicitly define the perturbed Fourier transform for H and obtain an eigenfunction expansion theorem for square integrable functions. This provides a complete proof of the inversion formula for that covers the class of short range potentials in (Forumala Presented). Such paradigm has applications in the study of scattering problems in connection with the spectral properties and asymptotic completeness of the wave operators.
