The aim of this paper is to introduced subclasses of Janowski functions with bounded boundary and bounded radius rotations of complex order b and of type ρ. And also to study the mapping properties of these classes under certain integral operators defined and studied by Breaz et. al recently.

The aim of this paper is to establish certain sufficient conditions for some subclasses of analytic functions using argument properties. Some applications of our work to the generalized Alexander integral operator is also given. Some sufficient conditions for spirallike functions with argument properties.

In this paper we will study the integral operator involving Bessel functions of the first kind and of order v. We will investigate the integral operator for the classes of starlike and convex functions in the open unit disk.

In this paper a new subclass of analytic functions associated with right half of the lemniscates of Bernoulli 2 2 2 2 2 2 0 x y x y has been introduced. An upper bound of the third Hankel determinant is determined for this class.

The aim of the present paper is to investigate coefficient estimates, Fekete-Szegő inequality, and upper bound of third Hankel determinant for some families of starlike and convex functions of reciprocal order.

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. Let A be the class of functions of… (More)

The aim of this paper is to define and study a class of analytic functions related to Bazilevic type functions in the open unit disc.This class is defined by using a convolution operator and the concept of bounded radius rotation of order ρ. A necessary condition, inclusion result, arc length and some other interesting properties of this class of functions… (More)
