Thanks pasmith,
I did try something like that, and basically got that same type of equation, but I’m not sure what to do with it next. Still searching…
My PDE:
F,x,t + A(x)*F(x,t)*[(x+t)^(-3/2)] = 0
A(x) is a known function of x.
Trying to separate F(x,t) like
F(x,t) = F1(x)*F2(t)*F3(x+t).
I’m getting desperate to solve,
any suggestions??
