Also, we obtain necessary and sufficient convolution conditions, distortion bounds and extreme points for these subclasses of functions.eninfo:eu-repo/semantics/closedAccessFunctions starlikeHarmonic functionsUnivalent functionsSubordinationHadamard productMultiplier transformationRuscheweyh operatorScience & technologyPhysical sciencesMathematics, appliedMathematicsArticle000498876400002192810612010.2298/PIM1920019
