THE ENERGY OF COEFFICIENT INEQUALITIES FOR CERTAIN SUBCLASSES OF ANALYTIC FUNCTIONS DEFINED BY DENIZ-OZKAN DIFFERENTIAL OPERATOR

ABSTRACT

By means of the Deniz-Ozkan differential operator, we introduce and investigate a new subclass of analytic functions. The various results obtained here for this function class include coefficient bounds and Fekete-Szego inequality.
