The Fekete-Szegö inequality for subclasses of analytic functions related to modified Sigmoid functions

Authors: MUHAMMET KAMALİ, HALİT ORHAN, MURAT ÇAĞLAR

Abstract: In this paper, the authors investigate the initial coefficient bounds for a new generalized subclass of analytic functions related to Sigmoid functions. Also, the relevant connections with the famous classical Fekete?Szegö inequality for these classes are discussed.

Keywords: Analytic functions, modified Hadamard product, Sigmoid function, Fekete-Szegö inequality
