Here, we give necessary conditions for the functions to belong to these subclasses, and distortion bound and growth theorems for the functions belonging to these classes.enginfo:eu-repo/semantics/openAccessCoefficient boundconvex functionq-derivativequasi close-to-q-convex functionarticle46620962108000824597700005
