In this paper we introduce a new class of meromorphic multivalent functions Σ*p(k, α, β) with positive coefficients. The main object of the present paper is to prove some properties for functions belonging to the class Σ*p(k, α, β). [ABSTRACT FROM AUTHOR]

In this paper, we drive several interesting subordination results of a certain classes of analytic functions defined by Dziok-Srivastava operator. [ABSTRACT FROM AUTHOR]

In this investigation, we obtain some applications of first order differential subordination and superordination results involving the multiplier transformation and Al-Oboudi operator for certain normalized analytic functions in the open unit disc. [ABSTRACT FROM AUTHOR]

In this paper we introduce a new subclass Mn(p, α, β) of meromorphically p-valent functions with positive coefficients in U* = {z : z ϵ C and 0 < ∣z∣ < 1} by using a linear operator Dn. The main object of this paper is to investigate the various important properties and characteristics of the class Mn(p, α, β). We also derive many results for the Hadamard products of functions belonging to the class Mn(p, α, β). [ABSTRACT FROM AUTHOR]

Making use of a differential operator and a given p-valent analytic function g the authors introduce and study two new classes TCg (p, q, n, α) and TCg (p, q, n,α) of p-valent analytic functions with negative coefficients. They also indicate relevant connections of these classes with sevesral other families of multivalent functions which were studied by earlier workers as well as new. [ABSTRACT FROM AUTHOR]
