This model is the so-called nonlinear Schrodinger equation that describes, for instance, the evolution of the electric field amplitude in nonlinear optical fibers. We propose and study a new way to implement a global space-time adaptive grid, based on interpolation properties of higher-order scaling functions.4 pages, compressed and uuencoded postcript file (final size: 720 Kbytes) Submitted to 7th SP Workshop on Signal Analysis and Array ProcessingCellular Automata and Lattice Gasestext
