Abstract
We investigate a new subclass of analytic
functions in the open unit disk 𝕌 which is defined by generalized
Ruscheweyh differential operator. Coefficient inequalities, extreme
points, and the integral means inequalities for the fractional derivatives of order p+η(0≤p≤n,0≤η<1) of functions belonging
to this subclass are obtained.
