Extreme points and support points of conformal mappings
Open Mathematics, 2019 There are three types of results in this paper. The first, extending a representation theorem on a conformal mapping that omits two values of equal modulus. This was due to Brickman and Wilken.

Coefficient estimates for a subclass of analytic functions by Srivastava-Attiya operator
, 2022 In this paper, we investigate bounds of the coefficients for subclass of analytic and bi-univalent functions. The results presented in this paper would generalize and improve some recent works and other authors. Mathematics Subject Classification (2010):

Application of Ruscheweyh q-differential operator to analytic functions of reciprocal order
, 2020 The core object of this paper is to define and study new class of analytic function using Ruscheweyh q-differential operator. We also investigate a number of useful properties such as inclusion relation, coefficient estimates, subordination result,for ...

Subclasses of analytic functions of complex order defined by q-derivative operator
, 2019 Using the q-derivative operator in conjunction with the principle of subordination between analytic functions, we introduce two subclasses of analytic functions in the open unit disk U.
