# References about non uniqueness of solution in ordinary differential equations

I am looking for some example of IVP with non unique solution. I already know the examples of $f(x,y)=k\sqrt{y}$ and $f(x,y)=k y^{2/3}$. Any book or link is welcome.

• Some more examples: math.stackexchange.com/questions/239284/…, Uniqueness and Nonuniqueness Criteria for Ordinary Differential Equations By Ratan Prakash Agarwal, Ravi P. Agarwal, V. Lakshmikantham, and search the web for notes with more examples. Regards – Amzoti Oct 29 '13 at 15:22
