Fuad S Al Sarari,Sridhar Latha,MASLINA DARUS 강원경기수학회 2017 한국수학논문집 Vol.25 No.3
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.
