Monge-Ampère Differential Equation

A second-order partial differential equation of the form

Hr+2Ks+Lt+M+N(rt-s^2)=0,
(1)

where H, K, L, M, and N are functions of x, y, z, p, and q, and r, s, t, p, and q are defined by

r=(partial^2z)/(partialx^2)
(2)
s=(partial^2z)/(partialxpartialy)
(3)
t=(partial^2z)/(partialy^2)
(4)
p=(partialz)/(partialx)
(5)
q=(partialz)/(partialy).
(6)

The solutions are given by a system of differential equations given by Iyanaga and Kawada (1980).

Other equations called the Monge-Ampère equation are

u_(xx)u_(yy)-u_(xy)^2=f(x,y,u,u_x,u_y)

(Moon and Spencer 1969, p. 171; Zwillinger 1997, p. 134) and

|u_(x_1x_1) u_(x_1x_2) ... x_(x_1x_n); u_(x_2x_1) u_(x_2x_2) ... x_(x_2x_n); | | ... |; u_(x_nx_1) u_(x_nx_2) ... u_(x_nx_n)|=f(x,u,del u)
