A CLASS OF MEROMORPHIC MULTIVALENT FUNCTIONS WITH POSITIVE COEFFICIENTS

In this paper, we introduce a class F(lambda,p)(n)(alpha,beta,gamma) of meromorphic multivalent functions in U* = {z : 0 < vertical bar z vertical bar < 1} by using a differential operator D(lambda,p)(n)f(z). We obtain coefficient estimates, distortion theorem, radius of convexity, closure theorems and integral transforms for the class F(lambda,p)(n)(alpha,beta,gamma). Several results involving the Hadamard products of functions belonging to the class F(lambda,p)(n)(alpha,beta,gamma) are also derived.
