On new classes of analytic functions with negative coefficients
We introduce the classes of analytic functions with negative coefficients by using the th order Ruscheweyh derivative. The object of the present paper is to show coefficient inequalities and some closure theorems for functions in . Further we consider the modified Hadamard product of functions in .
