On A Class of Multivalent Functions Defined by Ruscheweyh Derivative

In the present paper, we introduce a class V^δ_n,p,γ(A,B) of certain analytic functions. In our first result we show, by an inclusion relation, that the functions in V^δ_n,p,γ(A,B) are p-valent. Then we obtain class preserving integral operator, sharp coefficient estimate, a sufficient condition in terms of coefficients maximization theorem concerning coefficients x and closure theorem for the class V^δ_n,p,γ (A,B). Our results generalize corresponding results of Kumar and Shukla [Indian J. Pure Appl. Math. 15(1984)] and hence corresponding results of Chen [Soochow J. Math. 8(1982)] and Goel and Sohi[Indian J. Pure Appl.Math.11(1980)] follow.
