Abstract

Our goal is to develop spectral and scattering theories for the one-dimensional Schr\"odinger operator with a long-range potential q(x)q(x), x0x\geq 0. Traditionally, this problem is studied with a help of the Green-Liouville approximation. This requires conditions on the first two derivatives q(x)q' (x) and q(x)q'' (x). We suggest a new Ansatz that allows us to develop a consistent theory under the only assumption qL1q' \in L^1.
