SOME APPLICATIONS OF A LINEAR OPERATOR 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 .Coefficient bounds for functions belonging to these subclasses are determined. Further, an application involving fractional calculus we are also given.
