Fekete-Szeg? Inequality for a Subclass of Bi-univalent Functions Associated with Hohlov Operator and Quasi-subordination

摘要

In this paper, we introduce a new subclass of bi-univalent functions de-fined by quasi-subordination and Hohlov operator and obtain the coefficient estimates and Fekete-Szeg? inequality for function in this new subclass. The results presented in this paper improve or generalize the recent works of other authors.
