Hi. Could someone help me? In Boyd's book nonlinear optics equation 6.2.24
How to solve it?

Basically, it is a 4 variables first order partial differential equation. How to solve it analytically?

Thanks

I doubt many of us (if any) has this book, could you please post the equation for us to see? Go to "Go advanced" and click on the small $$\Sigma$$ sign above the text box to use LaTex. LaTex is coding that looks like this $$\frac{d^{2}x}{dt^{2}}+\frac{dx}{dt}=f(t)$$
