Abstract

In this paper, we de ne a new subclass of bi-univalent functions related to shell-like curves connected with Fibonacci numbers by using (p; q)-derivative and the coe cient estimates, Fekete-Szego inequalities are discussed for the functions belonging to this class.

Keywords

Bi-univalent functions, Fekete-Szego inequality, Fibonacci numbers, Shell-like curves and (p; q)-derivative.
