Certain Coefficient Inequalities For Some Subclasses Of p-Valent Functions

Somia Muftah Amsheri, Valentina Zharkova

Abstract


In the present paper we obtain Fekete-Szegö inequality and bounds for the coefficient a_p+1 for some subclasses of p-valent functions in the open unit disk involving certain fractional derivative operator. Results proved by various authors will follow as special cases from our theorems.

Keywords


p-valent function, subordination, starlike function, convex function, fractional derivative operator, Fekete-Szegö inequality
