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]

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]
