Certain Subclasses of Bi-Close-to-Convex Functions Associated with Quasi-Subordination
In the present investigation, we introduce certain new subclasses of the class of biunivalent functions in the open unit disc U=z:z<1 defined by quasi-subordination. We obtained estimates on the initial coefficients a2 and a3 for the functions in these subclasses. The results present in this pape...
