Abstract
For analytic function f(z) = z + a2z
2 + · · · in the open unit disc D, a new
fractional operator Dλf(z) is defined. Applying this fractional operator Dλf(z) and the principle
of subordination, we give new proofs for some classical results concerning the class S
∗
λ
(A, B, α) of
functions f(z).
