On a Certain Classes of Meromorphic Functions with Positive Coefficients
In this paper certain classes of meromorphic functions in punctured unit disk are defined. Some properties including coefficient inequalities, convolution and other interesting results are investigated.
متن کاملCERTAIN SUBCLASSES OF p−VALENT MEROMORPHIC FUNCTIONS INVOLVING CERTAIN OPERATOR
In this paper, a new subclass ∑α p,β(η, δ, μ, λ) of p−valent meromorphic functions defined by certain integral operator is introduced. Some interesting properties of this class are obtained.
متن کاملOn Certain Subclass of Meromorphic p-valent Functions with Negative Coefficients
We introduce a class Σ∗λ,p,α of meromorphic p-valent functions with negative coefficients. The main object of this paper is to investigate various important properties and characteristics of this class. Further many interesting results for the Hadamard product of functions belonging to the class Σ∗λ,p,α is obtained. 2000 Mathematics Subject Classification: 30C45.
متن کاملOn Certain Class of Meromorphic Functions with Positive Coefficients
In the present investigation we define a new class of meromorphic functions on the punctured unit disk Δ∗ := {z ∈ C : 0 < |z| < 1} by making use of the generalized Dziok–Srivastava operator Hl m [α1]. Coefficient inequalities, growth and distortion inequalities, as well as closure results are obtained. We also establish some results concerning the partial sums of meromorphic functions and neigh...
