A class of analytic functions defined by Salagean dekivatives and Fekete-Szeg inequality

Set A is a function class constituted by the analytic function f(z)=z+a2z2+…,which is analytical in unit circle E={z:z1}.In this paper,we introduced Salagean operators with the definition of the subclass Mα[n,β,σ,η] of analytic functions A.In the use of the elementary methods,we discussed Fekete-Szeg inequality of this class function and promoted some relevant results.
