摘要
利用从属关系定义了与贝努利双纽线有关且具有对称点的一类解析函数L*s,讨论了函数类L*s的三阶Hankel行列式H3(1),得到了该行列式的上界估计.其结果改进并推广了一些已有结论.
A class of analytic functions associated with lemniscate of Bernoulli and symmetric points was introduced,denoted by L*s. The Hankel determinant H3(1) for this class functions was investigated and the estimate of upper bound of the above determinant was obtained. The results improve and generalize some known results.
