Sharp Bounds on the Higher Order Schwarzian Derivatives for Janowski Classes
Higher order Schwarzian derivatives for normalized univalent functions were first considered by Schippers, and those of convex functions were considered by Dorff and Szynal. In the present investigation, higher order Schwarzian derivatives for the Janowski star-like and convex functions are consider...
