Abstract

Abstract In this article, we study the Fekete-Szegö functional associated with a new class of analytic functions related to the class of bounded turning by using the principle of quasi-subordination. We derived the coefficient estimates including the classical Fekete-Szegö inequality for functions belonging to this class. We also improved some existing results.

Fekete-Szegö一类与拟从属相关的非巴齐勒维奇函数的泛函

摘要本文利用拟隶属原理，研究了Fekete-Szegö泛函与一类新的与有界转向有关的解析函数的关系。我们导出了这类函数的系数估计，包括经典的Fekete-Szegö不等式。我们还改进了一些现有的结果。
