In the present paper, we study on the subclass of starlike functions of complex order with bounded radius rotation using q− difference operator denoted by R k (q, b) where k ≥ 2, q ∈ (0, 1) and b ∈ C\{0}. We investigate coefficient inequality, distortion theorem and radius of starlikeness for the class R k (q, b).2010 Mathematics Subject Classification. 30C45.
