Abstract
Let A denote the class of functions f which are analytic in the open unit disk U. The subclass of A consisting of univalent functions is denoted by M. In this paper, we also consider a subclass of M which is denoted by V, consisting of functions with negative coefficients. In addition, this paper also studies the qderivative operator. By combining the ideas, this paper introduced three subclasses of A with negative coefficients involving qderivative. Furthermore, the coefficient estimates, growth results and extreme points were obtained for all of these classes.
