In this paper, the classes S∗[A,B] and C[A,B] are discussed in terms of dual sets. Using duality, various geometric properties of mentioned class are analyzed. Problem of neighborhood as well as stability of convolution of S∗[A,B] and C[A,B] are studied. Some of our results generalize previously known results.
