In this paper, the authors determine the coefficient bounds for functions in certain subclasses of analytic functions related with the conic regions, which are introduced by using the concept of bounded boundary and bounded radius rotations. The effect of certain integral operator on these classes has also been examined.
Sarfraz Nawaz Malik, Mohsan Raza, Muhammad Arif and Saqib HussainLet A be the class of functions of the form 1) which are analytic in the unit disc E = {z : |z| < 1}. Also let K γ and C * γ denote the well-known classes of close-to-convex and quasi-convex functions of complex order γ (γ = 0) respectively, see for details [2,12]. Kanas and Wisniowska [5,6] studied the classes of β-uniformly convex functions denoted by β − U CV and the corresponding class of β-starlike functions β − ST related by the Alexandar type relation. Later Acu [1] considered the class of β-uniformly close-to-convex functions, denoted by β − U K and is defined as:
