On some applications of Ruscheweyh derivative

In this paper, we discuss a subclass Vk(β,b,δ)Vk(β,b,δ) of analytic functions, which was introduced and discussed by Latha and Nanjunda Rao (1994) [3]. Some results such as inclusion relationship, coefficient inequality and radius of convexity for this class are proved. We also observe that this class is preserved under the Bernardi integral transform.
