We introduce the classesKn*of analytic functions with negative coefficients by using thenth order Ruscheweyh derivative. The object of the present paper is to show coefficient inequalities and some closure theorems for functionsf(z)inKn*. Further we consider the modified Hadamard product of functionsfi(z)inKni*(n=1,2,…,m).
