May you please show me how to solve the following NLSE pde: iU_{z} + dU_{tt} = 0 where 1. d [\tex] = constant, and 2. [tex]U(z=0,t)=e^{(-t^{2})} It's the NLSE, the nonlinear terms and the loss terms are here considered negligible.

thanks so much for the explantation Arildno...

__________________________ I would say the nonlinear + dispersion terms tend to maintain the waveform as opposed to steepening as u propose... maybe you check up references on solitons/solitary waves and stuff - start with basic texts like Agrawal's Nonlinear Effects in Optical Fibers...
