There is a rich literature on estimation of second and third Hankel determinants for
normalised analytic functions in geometric function theory. It is also, therefore, natural to …

Several properties of the class $\mathcal {S}^* _ {r}(\alpha) $ of starlike functions of
reciprocal order $\alpha\,(0\leq\alpha< 1) $ defined on the open unit disk have been studied …

In this paper, we have determined the sharp lower and upper bounds on the fourth-order
Hermitian-Toeplitz determinant for starlike functions with real coefficients. We also obtained …

In this paper, we answer the questions raised in the paper [On the difference of inverse
coefficients of univalent functions, Symmetry, 2020, 12 (12), art. 2040, 14pp] by Sim and …

Let f (z) be analytic in the unit disk with f (0)= f (0)− 1= 0. For the following closeto-convex
subclasses:{(1− z) f (z)}> 0,{(1− z2) f (z)}> 0,{(1− z+ z2) f (z)}> 0 and {(1− z) 2 f (z)}> 0, we …
