主 题:Multi-scale analysis Modulation equation Kuramoto-Shivashinsky equation Ginzburg-Landau equation
摘 要:The main goal of this paper is to approximate the Kuramoto-Shivashinsky(K-S for short) equation on an unbounded domain near a change of bifurcation,where a band of dominant pattern is changing *** leads to a slow modulation of the dominant *** we consider PDEs with quadratic nonlinearities and derive rigorously the modulation equation,which is called the Ginzburg-Landau(G-L for short) equation,for the amplitudes of the dominating modes.
