A representation formula related to Schrodinger operators
Shijun Zheng
Let H be a Schrodinger operator on the real line, where the potential is in L^1 and L^2. We define the perturbed Fourier transform F for H and show that F is an isometry from the a…

Besov spaces for Schrodinger operators with barrier potentials
John J. Benedetto, Shijun Zheng
Let H be a Schrodinger operator with barrier potential on the real line. We define the Besov spaces for H by developing the associated Littlewood-Paley theory. This theory depends…
