On Certain Subclass of Analytic Functions Involving Salagean Operator

In this article,a new subclass Mm,n( α,β) = {f( z) : Re(Dmf( z)/Dnf( z)) β|Dmf( z)/Dnf( z)- 1 | + α( z∈U),α 1,β≤0,m∈N,n ∈N 0 } of univalent and analytic functions involving Salagean operator in the open disc U = { z: |z| 1} is introduced. The coefficients inequalities,distortion inequalities,extreme points and subordinating property are discussed by using solutions of inequalities tech- niques and theories of analytic functions. The sharp results are obtaind which generalize some know results.
