Abstract. Let A(p) be the class of functions f : z p +X ∞j=1 a j z p+j analytic in the openunit disc E. Let, for any integer n > −p, f n+p−1 (z) = z p +X ∞j=1 (p + j) n+p−1 z p+j . Wedefine f (−1)n+p−1 (z) by using convolution ∗ as f n+p− 1 ∗ f −1n+p− =z p (1 − z) n+p . A function p,analytic in E with p(0) = 1, is in the class P k (ρ) ifZ 2π0 Re p(z) − ρp − ρ dθ ≤ kπ, wherez = re iθ , k ≥ 2 and 0 ≤ ρ ≤ p. We use the class P k (ρ) to introduce a new class ofmultivalent analytic functions and define an integral operator L n+p−1 (f) = f −1+p−1 ∗ ffor f(z) belonging to this class. We derive some interesting properties of this generalizedintegral operator which include inclusion results and radius problems. 1.
