Solving PDE $u_t+f(u)u_x=0$ using its physical interpretation
I know how to use characteristics. I have a problem with that (mathoverflow.net/questions/436604/…) problem. So, I want to find another way to find weak solution.

@Bullet51 , I hope that there will be something like the discriminant on the quadratic equations.
