Abstract :
In this work, a new subclass of function, G (n, μ, ) :
n 2 N0, μ > 1, 0 6 6 1, was defined using the Sˇalˇagean differential
operator involving the modified sigmoid function and subordination
principle. The initial coefficient bounds and the Fekete-Szego functional
of this class were obtained.
