在目前的调查中,我们发现估计的系数|A2|和|A3|对于函数类B中的函数,有一个新的定义:本文的结果改进或推广了Porwal和Darus [8]最近的工作。2000年数学学科分类:30C45。
In the present investigation, we find estimates on the coefficients |a2| and |a3| for functions in the function class BΣ (n, λ, φ) . The results presented in this paper improve or generalize the recent work of Porwal and Darus [8]. 2000 Mathematics Subject Classification: 30C45.
