Özet

By means of a differential operator, we introduce and investigate some new subclasses of p-valently analytic functions with negative coefficients, which are starlike or convex of complex order. Relevant connections of the definitions and results presented in this paper with those obtained in several earlier works on the subject are also pointed out.
