Neighborhoods and Partial Sums of Certain Meromorphically Multivalent Functions
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.

متن کاملOn Certain Classes of Meromorphically Multivalent Functions Involving the Generalized Hypergeometric Functions
0 ∣∣∣∣Reh(z)− ρ 1− ρ ∣∣∣∣ dθ ≤ kπ, z = re, where k > 2 and 0 ≤ ρ < 1. This class was introduced by Padmanabhan et al. in [9]. We note that Pk(0) = Pk, see Pinchuk [11], P2(ρ) = P (ρ), the class of analytic functions with positive real part greater than ρ and P2(0) = P, the class of functions with positive real part. From (1.2) we can easily deduce that h(z) ∈ Pk(ρ) if, and only if, there exists...
متن کاملA Certain Subclass of Meromorphically Multivalent Analytic Functions with Negative Coefficients
Corresponding Author: Rabha W. Ibrahim Faculty of Computer Science and IT, University Malaya, 50603 Kuala Lumpur, Malaysia Email: [email protected] Abstract: The paper aims to introduce a certain subclass S * g(A,B,α,p,j) of the class Σ * (p) of meromorphically multivalent functions with negative coefficients, defined by using the definitions of Hadamard product and subordination for two f...
متن کاملA subclass of Meromorphically Multivalent Functions Associated with an Operator
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...
