Özet
In the present investigation, we consider two new subclasses N-Sigma(mu) (alpha, lambda) and N-Sigma(mu) (beta, lambda) of bi-univalent functions defined in the open unit disk U = {z : vertical bar z vertical bar < 1}. Besides, we find upper bounds for the second and third coefficients for functions in these new subclasses.
