Özet
The aim of this investigation is to introduce two new subclasses of the class sigma related with the generalized Salagean differential operator and find estimates on the coefficients vertical bar a(2)vertical bar and vertical bar a(3)vertical bar for functions in these new subclasses. Moreover, we give some interesting results by using the relationship between Salagean's differential operator and generalized Salagean differential operator.
