摘要
利用从属关系定义了贝努利左半区域内的一类解析函数BLα(0≤α≤1),并研究了该函数类BLα的三阶Hankel行列式H 3(1),得到其上界估计.除此之外,给出了一些特殊的例子.
In this paper,we introduce a class of analytic functions BLα(0≤α≤1)in the left-half bounded domain of lemniscate of Bernoulli,which are defined by using subordination relationship,and investigate the third Hankel determinant H 3(1)of BLα,and its upper bound is obtained.In addition,some special cases of the results obtained are considered.
