چکیده
|
In this paper,we define and study some subclasses of multivalent analytic functions of higher order in the unit disc. these classes generalize some classes previously studied. we obtain coefficient inequalities,distortion theorems,extreme points,and integral mean inequalities. we derive some results as special cases. © 2017 xiaofei li et al.
