Fourth hankel determinant for a subclass of starlike functions
Let B be the class of normalized starlike functions f z which are analytic on an open unit disc E z z { : 1} and satisfy Re ' '' 0 f z zf z for some 0 1 and 0 1 . In this paper, we will obtain a sharp bound of the fourth Hankel determinant, H4 1...
