Certain classes of meromorphic multivalent functions with positive coefficients

The main object of the present paper is to introduce certain novel classes of meromorphic multivalent functions Qλ∗[p,α,A,B], and ∑p,λ∗[α,β]. In this paper, we obtain coefficient estimates, distortion theorems, radii of convexity and closure theorems for the class Qλ∗[p,α,A,B]. Several interesting results involving the Hadamard product of functions belonging to the classes Qλ∗[p,α,A,B],∑p,λ∗[α,β] and ∑p∗[α,β] are also derived. Also integral transforms of functions in the classes ∑p,λ∗[α,β] and ∑p∗[α,β] are studied.
