Özet
In this paper, we introduce and investigate a new subclass (Formula presented.) of analytic functions defined by the (Formula presented.) -derivative in the setting of Geometric Function Theory. This class extends the classical subclass (Formula presented.) and reduces to it when the parameters (Formula presented.) and (Formula presented.) tend to (Formula presented.). By means of coefficient estimates, we obtain a sufficient condition for the general class and a necessary and sufficient condition for the corresponding negative-coefficient subclass. These results are then applied to the (Formula presented.) -Poisson distribution series and to a related linear operator. The graphical analysis included in the final section illustrates the geometric behavior of the introduced functions and highlights the effects of the parameters.
