The problems of finding similar bounds on the Schwarzian derivatives that would imply univalence, starlikeness or convexity of functions were investigated by a number of authors including Gabriel (4), Friedland and Nehari (3), and Ozaki and Nunokawa (11).
The first result leads to sufficient conditions for univalence.
