Hello,

I try to solve a patial dérivates equation with two variables but I could
not under mathématica, my system is :

(a1+b1.exp(-x^2/c1))dE(x, t)/dx + a2.E(x, t).(d^2E(x, t)/dx^2).dE(x, t)/dt+
a3.dE(x, t)/dx.d^2E(x, t)/dt^2+ (a4+b4.exp(-x^2/c1))E(x, t).d^2E(x, t)/dx^2+
a5+b5.exp(-x^2/c1))dE(x, t)/dx dE(x, t)/dt+ a6.exp(-x^2/c1))E(x, t)=0

 such as, a1, b1, c1, a2, a3, a4, b4, a5, b5, a6 ; constants.

I thank you for giving me at least an idea for the solution of this very
complex equation.
