On certain subclasses of starlike and convex functions associated with Pascal distribution series

Şeker, Bilal; Sevtap, Sümer Eker (TUBITAK, 2020)

In this article, we introduced a new power series whose coefficients are probabilities of the Pascal distribution. We investigated new approaches between the Pascal distribution series and some subclasses of normalized ...
On subclasses of bi-convex functions defined by Tremblay fractional derivative operator

Eker, Sevtap Sümer; Şeker, Bilal (Babes-Bolyai University, 2019)

We introduce and investigate new subclasses of analytic and biunivalent functions defined by modified Tremblay operator in the open unit disk. Also we obtain upper bounds for the coefficients of functions belonging to these ...
