Abstract

A certain subclass Bm(p,α,λ,ℓ,A,B) consisting of meromorphic p-valent functions with alternating coefficient in U∗={z:z∈C:0<|z|<1} is introduced. In this paper we obtain coefficient inequalities, distortion theorem, closure theorems and class preserving integral operators for functions in the class Bm(p,α,λ,ℓ,A,B) are obtained .
