NEW SUBCLASSES OF MEROMORPHIC p−VALENT FUNCTIONS
In this paper, we introduce two subclasses Ωp(α) and Λ ∗ p(α) of meromorphic pvalent functions in the punctured diskD = {z : 0 < |z| < 1}. Coefficient inequalities, distortion theorems, the radii of starlikeness and convexity, closure theorems and Hadamard product ( or convolution) of functions belonging to these classes are obtained.
متن کاملSome Inclusion Properties of Certain Subclasses of P-valent Meromorphic Functions Associated with a New Operator
In this paper we introduce new subclasses of p-valent starlike, pvalent convex, p-valent close-to-convex and p-valent quasi-convex meromorphic functions and investigate some inclusion properties of these subclasses and investigate various inclusion properties and integral-preserving properties for the p-valent meromorphic function classes.
متن کاملSome Subclasses of Meromorphic Functions Associated with a Family of Integral Operators
Making use of the principle of subordination between analytic functions and a family of integral operators defined on the space of meromorphic functions, we introduce and investigate some new subclasses of meromorphic functions. Such results as inclusion relationships and integralpreserving properties associated with these subclasses are proved. Several subordination and superordination results...
متن کاملSome Inclusion Relationships for Certain Subclasses of Meromorphic Functions Associated with a Family of Integral Operators
We define a family of integral operators using multiplier transformation on the space of normalized meromorphic functions and introduce several new subclasses using this operator. We investigate various inclusion relations for these subclasses and some interesting applications involving a certain class of the integral operator are also considered.
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.
