A Certain Subclass of Multivalent Analytic Functions Defined by the q-Difference Operator Related to the Janowski Functions. Mathematics, 9(14), 1-16. https://doi.org/10.3390/math9141706.https://doi.org/10.3390/math9141706http://hdl.handle.net/1828/13201A class of p-valent analytic functions is introduced using the q-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 theorems, radii of convexity and starlikeness, closure theorems and partial sums, are discussed in this paper.enanalytic functionsq-difference operatorunivalent and multivalent functionsJanowski functionsFekete-Szego inequalitydistortion theoremradii of starlikeness and convexitypartial sumclosure theoremsArticleDepartment of Mathematics and Statistics
