Abstract

The aim of this investigation is to introduce two new subclasses of the class σ related with the generalized Sălăgean differential operator and find estimates on the coefficients |a₂| and |a₃| for functions in these new subclasses. Moreover, we give some interesting results by using the relationship between Sălăgean's differential operator and generalized Sălăgean differential operator.
