چکیده
|
In this work, a new subclass of function, gγ(n, µ, λ) : n ∈ n0, µ ≥ 1, 0 ≤ λ ≤ 1, was defined using the salagean differential operator involving the modified sigmoid function and subordination principle. the initial coefficient bounds and the fekete-szego functional of this class were obtained.
