Generalised differential operator defined by analytic functions associated with negative coefficients
We define a new generalised derivative operator Dm,s,µ,b for the class A of analytic functions in the unit disc U = {z∈C:|z|<1} . This operator has generalised many well known operators studied by many different authors. Also in this paper we introduce a new subclass of A using generalised de...

We define a new generalised derivative operator Dm,s,µ,b
for the class A of analytic functions in
the unit disc U = {z∈C:|z|<1} . This operator has generalised many well known operators
studied by many different authors. Also in this paper we introduce a new subclass of A using
generalised derivative operator. Coefficient inequalities, distortion theorems, and extreme
points of analytic functions belonging to the subclass are given |
