As far as I know, weak solutions are not used much in ODE theory, because you can accomplish most of what you want using only the concept of strong solutions. This is strong contrast to PDE theory, where you probably could avoid using weak solutions but using them facilitates significantly the development of the techniques and proofs required. | |
