Precisely, we give a necessary and sufficient coefficient condition for functions in this class. Coefficient estimates, extreme points, convex linear combination, Radii of starlikeness and convexity and finally partial sum property are investigated.https://scma.maragheh.ac.ir/article_46513_b8aeda0c259850ac0e67ca9c643a79ab.pdf
