【Abstract】 Let A(n) be the class of normalized andlytic function f(z)=Z+anZn+... (n≥2. |Z|< 1). Let S (a. β, n) denote all functions satisfying condition Re{(1-b)f (Z)/Z+βf’ (Z)}>a in A (n).where β≥0. 0≤a<1. When β=0, the class S (a. β. n) becomes class s(a, n) [1] . This paper obtain that the representation formulas by intergration. estimation of coefficients and distortion theorem with repect to functions in the class S (a. β. n). These results are also the extension of well-know results in [1]and [2].更多还原
