# Uniqueness Theorem query.

Is there any proof which would show that the uniqueness theorem does not imply complete uniqueness of a ODE solution?

Would it have any relation between the interval where uniqueness is assumed to exist and the maximal interval of existence?

Thanks :)

Did you mean as in Theorem 2.4.1 or somethings else?. Regards – Amzoti Feb 15 '13 at 23:46

The usual example is something along the lines of $$y' = 2 \sqrt y, \; \; y(0) = 0.$$ Then two legitimate solutions for $x \geq 0$ are $$y = 0$$ OR $$y = x^2.$$
