Other equations

Besides the "big three" of nonlinear wave equations, nonlinear schrodinger equations, and KdV-type equations, there are a number of other nonlinear dispersive and wave equations of interest:

• The Schrodinger-Ginsberg-Landau equation
• The Vlasov-Maxwell equation
• The Kadomtsev-Petviashvili equations (KP-I and KP-II)
• The Zakharov equation (on R, on T, on R^2, or on R^3)
• Klein-Gordon-Zakharov
• Other wave-Schrodinger systems (Ishimori, Davey-Stewartson, Yukawa, etc.)
• Higher-order dispersive systems
