Abstract

In this manuscript, introduction of new subclasses of bi-univalent functions in the open disk was defined. Moreover,by using Salagean operator,in these new subclasses for func- tions, upper bounds for the second and third coefficients were found. Presented results are a generalization of the results obtained by Srivastava et al.[10], Frasin and Aouf [5] and Caglar et al.[3]
