Consider the generic form of a second order linear partial differential equation in 2 variables with constant coefficients: a u xx + b u xy + c u yy + d u x + e u y + f u = g(x,y). For the equation to be of second order, a, b, and c cannot all be zero. Define its discriminant to be b2 – 4ac.

An equation is said to be of n-th order if the highest derivative which occurs is of order n. An equation is said to be linear if the unknown function and its deriva-tives are linear in F. For example, a(x,y)ux +b(x,y)uy +c(x,y)u = f(x,y), where the functions a, b, c and f are given, is a linear equation of first order.
