• A Study of Third Hankel Determinant Problem for Certain Subfamilies of Analytic Functions Involving Cardioid Domain (2019, unknown): “Specifically, the absolute sharp bounds of the functional H2,2 ( f ) = a2a4 − a(2)3 were found in [18,19] for each of the families C, S∗ and R, where the family R contains functions of bounded turning.”
• THIRD ORDER HANKEL DETERMINANT FOR CERTAIN UNIVALENT FUNCTIONS (2015, unknown): “, [21], |a3 − a(2)2| ≤ 2/3 [3], and |a2a4 − a(2)3| ≤ 4/9 [11].”
• Coefficient inequality for certain classes of analytic functions (2016, unknown): “Janteng, Halim and Darus [8] have considered the functional |a2a4−a3| and found a sharp bound for the function f in the subclass RT of S, consisting of functions whose derivative has a positive real part studied by Mac Gregor [10].”
• Third Hankel determinant for bounded turning functions of order alpha (2015, unknown): “The sharp upper bound to the second Hankel functional H2(2) for the subclass RT of S, consisting of functions whose derivative has a positive real part, studied by Mac Gregor [7] was obtained by Janteng [8].”
• Third Hankel determinant for univalent starlike functions (2021, unknown): “For the following three classes: S∗ of starlike functions,K of convex functions andRof functionswith bounded turning they proved in [9,10] that |H2(2)| is bounded by 1, 1/8 and 4/9, respectively.”
