Applications Poisson Distribution and Ruscheweyh Derivative Operator for Bi-Univalent Functions


Abbas Kareem Wanas, Janusz Sokół




In this paper we establish upper bounds for the second and third coefficients of holomorphic and bi-univalent functions in a new family which involve the Bazilevič functions and $\beta$-pseudo-starlike functions under a new operator joining Poisson distribution with Ruscheweyh derivative operator. Also, we discuss Fekete-Szegö problem of functions in this family.
