Talk:Stuart–Landau equation

More general formulations
In Kuramoto, Y.: Chemical oscillations, waves, and turbulence more general, a more general equation derived by Haken and Sauermann (Haken and Sauermann (1963):Frequency Shifts of Laser Modes in Solid State and Gaseous Systems) is mentioned. Unfortunately, I couldn't find out, which one. Maybe also a reference to Ginzburg-Landau would be interesting. --W.pseudon (talk) 11:20, 8 August 2019 (UTC)
