Fekete-Szegö inequalities associated with k-th root transformation based on quasi-subordination

Abstract

Recently, Haji Mohd and Darus [1] revived the study of coefficient problems for univalent functions associated with quasi-subordination. Inspired largely by this article, we provide coefficient estimates with k-th root transform for certain subclasses of S defined by quasi-subordination.
