A few results on Janowski functions associated with $k$-symmetric points

Fuad S Al Sarari, Sridhar Latha, Maslina Darus


The purpose of the present paper is to introduce and study new subclasses of analytic functions which generalize the classes of Janowski functions with respect to $k$-symmetric points. We also study certain interesting properties like covering theorem, convolution condition, neighborhood results and argument theorem.
