FOURTH HANKEL DETERMINANT FOR A SUBCLASS OF STARLIKE FUNCTIONS; [Penentu Hankel Keempat untuk Suatu Subkelas Fungsi Bak Bintang]
Let B be the class of normalized starlike functions f (z) which are analytic on an open unit disc (Formula Presented) and satisfy (Formula Presented) for some 0 < α ≤ 1 and 0 ≤ β < 1. In this paper, we will obtain a sharp bound of the fourth Hankel determinant, H4 (1). © 2020, Penerbit Univers...
