A Certain Subclass of Multivalent Analytic Functions Defined by the <i>q</i>-Difference Operator Related to the Janowski Functions

A class of <i>p</i>-valent analytic functions is introduced using the <i>q</i>-difference operator and the familiar Janowski functions. Several properties of functions in the class, such as the Fekete–Szegö inequality, coefficient estimates, necessary and sufficient conditions, distortion and growth...
