Abstract:
The bipolar(defocusing nonlinear) Schr dinger-Poisson system and quasilinear Schr dinger-Poisson equations are studied. The wellposedness, large time behavior and modified scattering theory is established for the Cauchy problem to the bipolar(defocusing nonlinear) Schr dinger-Poisson systems. The initia-l (Dirichlet) boundary problem for a high field version of the Schr dinger-Poisson equat ions, quas-i linear Schr dinger-Poisson equat ions, which include a nonlinear term in the Poisson equation corresponding to a field-dependent dielectric constant and an effect ive potent ial in the Schr dinger equations on the unit cube are also discussed.
