Abstract

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