p. 303 - 310 Certain classes of p-valent functions associated with Wright's generalized hypergeometric functions G. Murugusundaramoorthy Received: August 26, 2008; Revised: January 3, 2009; Accepted: February 6, 2009 Abstract. The Wright's generalized hypergeometric function is used here to introduce a new class of p-valent functions WTp(l, a, b) defined in the open unit disc and investigate its various characteristics. Further we obtained distortion bounds, extreme points and radii of close-to-convexity, starlikeness and convexity for functions belonging to the class WTp(l, a, b). Keywords: Analytic, p-valent; starlikeness; convexity; Hadamard product (convolution).
