Spatio-temporal bifurcations in the driven nonlinear drift wave equation
The nonlinear drift wave equation with wave-like driving term is analysed numerically. The location of coexisting attractors, the smooth bifurcations of solutions on them and the catastrophic bifurcations between them are investigated. A global bifurcation of the blue sky catastrophe type is made plausible. Several routes to chaos in the time domain (continuous spectrum) are observed. They may or may not be connected with spatial chaos (soliton-type turbulence). Fourier analysis in space and time reveals the nature of the solutions outside the continua.
