Abstract
Let T(_n^α)(β) denote the class of functions f(z)=z+∑_(k=2)^∞▒〖a_k z^k 〗, univalent and analytic in the unit disk U={z∈ C:|z|<1} such that Re(D^n [〖f(z)〗^α])/z^α>β, z∈U,n∈{0}∪N,α>0,0≤β<1 and D^n is the salagean differential operator, in this paper, we establish some coefficient bounds for functions of the class T(_n^α)(β).
