We investigate a new subclass of analytic
functions in the open unit disk which is defined by generalized
Ruscheweyh differential operator. Coefficient inequalities, extreme
points, and the integral means inequalities for the fractional derivatives of order of functions belonging
to this subclass are obtained.
