In this paper, we define some new class, B k (a, b, c, p, n, α, ρ) by using the integral operators I p,n(a, b, c)f(z).We also derive some interesting properties of functions belonging to the class B k (a, b, c, p, n, α, ρ). Our results generalizing the works of Owa and Cho, see [2, 10]. 2000 Mathematics Subject Classification: 30C45, 30C50.

An extension of k-uniformly starlike and convex functions are introduced by making use of an integral operator. Inclusion relations and coefficient bounds for these classes are determined and consequently, some known results are generalized. 2000 Mathematics Subject Classification: Primary 30C45; Secondary 30C50.

In this paper, we introduce a class Nk(p, λ, μ, ρ). We use a method of the mathematical induction and study some of the interesting properties of the operators I n (f(z)) = α+ 1 zα+1 z ∫ 0 t(I n−1(f(t))dt, where n ∈ N, α > −1, in the class Nk(p, λ, μ, ρ). 2000 Mathematics Subject Classification: 30C45, 30C50.

Let A(ω) denote the class of functions of the form f(z) = (z−ω)+ a2(z−ω)+ ... normalized by f(ω) = 0 and f ′(ω)− 1 = 0 and which are anal;ytic in the unit disk E = {z : |z| < 1}. We define operators Lω,n : A(ω) → A(ω) using the convolution ∗ and we use this operators to define and study a refinement by way of new generalization of some subclasses of analytic and univalent functions and properti...
