This paper discusses the function class Hβ(a) of the from f(z)=z ∑k=(n 1)^ ∞, which satisfies the conditon Re[f‘(Z) βzf″(z)]>a, (0≤a<1) in |z|<1, with its inclusion relation ,neighborhood properties and the deviation theorem ,convolution properties in the case when f(z) has negative coefficients. 相似文献
