These grids are of an adaptive grid type. Solving the boundary value problem of suitable Schrodinger equations on these grids leads to completely new and unexpected analytic properties of the underlying function spaces. Some of them are presented in this work. Copyright 2009 Andreas Ruffing et al.

Introduction It is well known that solving Schrodinger s equation is a prominent L2-boundary value problem. In this article we want to become familiar with some of the dynamic equations that arise in context of solving the Schrodinger equation on a suitable time scale where the expression time scale is in the context of this article related to the spatial variables. The Schrodinger equation is the partial differential equation t e R d2 d2 d2 . . d 1 -dx2 dy2 dz2 Ax y z Ax y z t i-y x-w---- i- where the function V Q c R3 R yields information on the .
