[edit] Roots of the Schwarzian Derivative

I am quite interested in knowing if there are any theorems / results concerning positive real roots of the Schwarzian derivative. There are many results where negative roots are concerned, but the particular functions I am studying all have positive roots. Anyone have any info?

[John McKay] Why can this not be referred to as Schwarz derivative ? It makes the search more consistent - and is used too. [John McKay]74.57.27.5 16:55, 13 August 2007 (UTC)

Would it not be better to multiply the SD by 2 ? Integers are better than fractions. [John McKay]133.6.130.119 (talk) 03:52, 4 June 2008 (UTC)
