What is Extended Fisher-Kolmogorov (EFK)?
There are many references to it, but I failed to find what is actually is. Is it some kind of non-linear differential equation? Does it describe physical systems?

Short answer would be: It is a nonlinear PDE, usually stated as $$u_t+\gamma u_{xxxx}-u_{xx}-u+u^3=0 $$ as introduced in Dee & van Sarloos' paper. Most authors like to emphasize its application in modeling of phase transitions at critical points. |
