Subclasses of analytic functions associated with the generalized hypergeometric function

Using the generalized hypergeometric function, we study a class Φkp(q,s;A,B,λ) of analytic functions with negative coefficients. Coefficient estimates, distortion theorem, extreme points and the radii of close-to-convexity and convexity for this class are given. We also derive many results for the modified Hadamard product of functions belonging to the class Φkp(q,s;A,B,λ).
