The authors would like to thank the referees for their helpful suggestions which essentially improved the presentation of this paper. Abstract. In this paper, we introduce a new subclass of meromorphic functions and investigate inclusion relationships and properties of a certain class of meromorphically p-valent functions, which are defined by means of the familiar operator involving the genera...

By making use of the familiar concept of neighborhoods of analytic functions, the author proves an inclusion relations associated with the (n, δ)−neighborhoods of a subclass Q k [p, α; A, B] which was introduced by Srivastava, Hossen and Aouf. The partial sums of the functions in Q k [p, α; A, B] are also considered.

In this paper authors introduced two new subclasses ∑ρτςξ mp α, β, η and ∑ (α, β, η) + ρτςξ mp of meromorphically multivalent functions which aredefined by means of a new differential operator. By making use of the principle of differential subordination, authors investigate several inclusion relationships and properties of certain subclasses which are defined here by means of a differential op...
