Özet

In this paper, we introduce and investigate a new subclass H-Sigma(h,) (p) (lambda; Theta) of analytic and bi-univalent functions in the open unit disk U : For functions belonging to this class, we obtain estimates on the first two Taylor-Maclaurin coefficients vertical bar a(2)vertical bar and vertical bar a(3)vertical bar.
