In this paper, we introduce new subclasses R-Sigma,b,c(mu,alpha) (lambda, delta, tau, Phi) and K-Sigma,b,c(mu,alpha) (lambda, delta, eta, Phi) of biunivalent functions in the open unit disk U by using quasi-subordination conditions and determine estimates of the coefficients vertical bar a(2)vertical bar and vertical bar a(3)vertical bar for functions of these subclasses. We discuss the improved results for the associated classes involving many of the new and well-known consequences. We notice that there is symmetry in the results obtained for the new subclasses R-Sigma,b,c(mu,alpha) (lambda, delta, tau, Phi) and K-Sigma,b,c(mu,alpha) (lambda, delta, tau, Phi), as there is a symmetry for the estimations of the coefficients a(2) and a(3) for all the subclasses defind in our this paper. |
