Time decay for Schroedinger equation with rough potentials
Shijun Zheng
We obtain certain time decay and regularity estimates for 3D Schroedinger equation with a potential in the Kato class by using Besov spaces associated with Schroedinger operators.

Function spaces associated with Schroedinger operators: the Poeschl-Teller potential
Gestur Olafsson, Shijun Zheng
We address the function space theory associated with the Schroedinger operator H. The discussion is featured with the Poeschl-Teller potential in quantum physics. Using biorthogona…
