某类解析函数子类的Fekete-Szegö不等式

摘要

The coefficient of fonctionelle ||a3-μa22 on the class of D(λαβ) functions was accurate-ly estimated,using Fekete-Szegö inequality for the class of real component functions. On this basis, Fekete-Szegö inequalities for the classes of functions defined by Hadamard convolution were obtained.%利用正实部函数的Fekete-Szegö不等式，对D(λ、α、β)函数类上的系数泛函||a3-μa22作了精确估计，在此基础上得到了利用Hadamard卷积定义的新函数类上的Fekete-Szegö不等式。
