On Subclasses of Analytic Functions with respect to Symmetrical Points

Some Coefficient Inequalities for Certain Subclasses of Analytic Functions with respect to k-Symmetric Points

In the present paper, we introduce two new subclasses B (k) λ (α) and L (k) λ (α) of analytic functions with respect to k-symmetric points. Some coefficient inequalities for functions belonging to these classes and their subclasses with positive coefficients are provided.

Some Subclasses of Analytic Functions with Respect to 2k-Symmetric Conjugate Points

In the present paper, we introduce two new subclasses P sc (λ, α) and Q sc (λ, α) of analytic functions with respect to 2k-symmetric conjugate points. Such results as integral representations, convolution conditions and coefficient inequalities for these classes are provided. 2000 Mathematics Subject Classification. Primary 30C45.

Some Properties of Certain Subclasses of Close-to-Convex and Quasi-convex Functions with Respect to 2k-Symmetric Conjugate Points

Some Classes of Analytic Functions Related with Functions of Bounded Radius Rotation with Respect to Symmetrical Points

In this paper, we introduce a class Rk(γ) of analytic functions of bounded radius rotation with respect to symmetrical points and study some of its basic properties. Using this concept, two other classes T s k (δ ,γ) , K s k (δ ,γ) are also defined. We study coefficient results, arc-length and radius problems for these classes.
