BLOWDISOL · BLOW UP, DISPERSION AND SOLITONS""

Many physical models involve nonlinear dispersive problems, like waveor laser propagation, plasmas, ferromagnetism, etc. So far, the mathematical under-standing of these equations is rather poor. In particular, we know little about thedetailed qualitative behavior of their solutions. Our point is that an apparent com-plexity hides universal properties of these models
