Hi all,
I understand some PDE is linear like
[itex]\frac{\partial f}{\partial t}+\frac{\partial f}{\partial x}=0[/itex]
while some PDE is nonlinear like
[itex]\frac{\partial f}{\partial t}+f\frac{\partial f}{\partial x}=0[/itex]
Some PDE is weak nonlinear and some is strong nonlinear.
I am wondering whether there is any quantitative measure of the nonlinearity? Many thank!
Joseph
