Abstract

The stability of stationary patterns and travelling waves against arbitrary fluctuations in spatially extended systems are investigated for the first time near the codimension-2 point. An important result is that travelling waves (and also standing waves) lose stability in some range via Benjamin-Feir resonance if the stationary pattern bifurcates inversely, in qualitative agreement with measurements on binary fluid mixtures. The results presented could stimulate further investigations.
