Coefficient estimates for certain subclasses of spiral-like functions of complex order

In this work, we introduce and investigate two interesting subclasses Mg(n,λ,b)andMg(n,λ,b;u) of analytic functions of complex order, which are defined here by means of the familiar the Sălăgean derivative operator. For functions belonging to each of these subclasses Mg(n,λ,b)andMg(n,λ,b;u), we obtain several results involving (for example) coefficient bounds. The results presented here would generalize many known results.
