Coefficient estimates for families of bi-univalent functions defined by Ruscheweyh derivative operator

Publikováno v: Mathematica Moravica, Vol 25, Iss 1, Pp 71-80 (2021)

The main purpose of this manuscript is to find upper bounds for the second and third Taylor-Maclaurin coefficients for two families of holomorphic and bi-univalent functions associated with Ruscheweyh derivative operator. Further, we point out certai

Strong differential sandwich results of l-pseudo-starlike functions with respect to symmetrical points

Autor: Srivastava H.M., Kareem Wanas Abbas

Publikováno v: Mathematica Moravica, Vol 23, Iss 2, Pp 45-58 (2019)

In the present investigation, by considering suitable classes of admissible functions, we establish strong differential subordination and superordination properties for l-pseudo-starlike functions with respect to symmetrical points in the open unit d
