The Fekete–Szegö functional associated with k-th root transformation using quasi-subordination

Abstract

Quasi subordination is an essential concept in the area of complex function theory. It is an remarkable topic which collaborate the concept of both subordination and majorization. In this article, we estimate the Fekete–Szego Functional with k-th root transform for certain classes of analytic univalent functions using quasi-subordination. The authors sincerely hope this article will refresh this concept and persuade the other young researchers to work in this quasi subordination in the near future in the area of complex function theory.
