Some Applications Of A Linear Operator To A Certain Subclasses Of Analytic Functions With Negative Coefficients

Abstract

The main object of this paper is to introduce and study the new subclasses , , ( , , , ) m TS l a c     and , , ( , , , ) m TR l a c     of analytic functions with negative coefficients defined by a linear operator . Coefficients inequalities for functions belonging to these subclasses are determined. In addition, radii of close-to-convexity, starlikeness and convexity, closure theorems are obtained.
