摘要：
In this paper, we introduce new and qualitative subclasses B-epsilon(kappa, alpha, sigma), B-gamma (kappa, alpha, sigma) and B-s,B-t(kappa, alpha, sigma) of bi-univalent functions. The coefficient bounds and Fekete-Szego inequalities for functions belonging to these subclasses are obtained. Also, we will get a variety of new results through special cases of our main results.
