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 Benjamin-Ono equation
• The Vlasov-Maxwell equation
• The Kadomtsev-Petviashvili equations (KP-I and KP-II)
• Wave-Schrodinger systems (Zakharov, Klein-Gordon-Zakharov, Ishimori, Davey-Stewartson, Yukawa, etc.)
• The nonlinear Schrodinger-Airy system
• Higher-order dispersive systems (e.g. the KdV hierarchy)
