Fekete-Szegö inequalities for a new general subclass of analytic functions involving the (p,q)-derivative operator Commun. Korean Math. Soc. Published online May 13, 2022 Serap Bulut Kocaeli University Abstract : In this work, we introduce a new subclass of analytic functions of complex order involving the (p,q)-derivative operator defined in the open unit disc. For this class, several Fekete-Szegö type coefficient inequalities are derived. We obtain the results of Srivastava et al. [RACSAM 113 (2019), 3563-3584] as consequences of the main theorem in this study.
