Estimate on the second Hankel functional for functions whose derivative has a positive real part
Denote to be the class of functions which are analytic, normalised and univalent in the open unit disc D-{z:|z|<1}. Also denote to represent the subclass of S whose derivative has a positive real part. Next, write f (z)-z+∑ a z where a is a complex constant and denote the qth Hankel determinant f...
