SOME SUBCLASSES OF ANALYTIC FUNCTIONS WITH RESPECT TO $k$-SYMMETRIC POINTS

ZHI-GANG WANG, DI SONG

Abstract

In the present paper, we introduce two new subclasses $\mathcal P^{(k)}(\lambda, \alpha)$ and $\mathcal Q^{(k)}(\lambda, \alpha)$ of analytic functions with respect to $k$-symmetric points. Such results as integral representations, convolution properties and coefficient inequalities for these function classes are proven.
