论文摘要
获得了单位磁盘$ \ Mathbb {d} $中标准化分析功能$ f $的初始系数的估计值，以便$ f $ and $ f^{ - 1} $的分析扩展至$ \ m athbb {d} $属于某些单位函数的某些子类别。获得的界限改善了一些现有的已知界限。
Estimates are obtained for the initial coefficients of a normalized analytic function $f$ in the unit disk $\mathbb{D}$ such that $f$ and the analytic extension of $f^{-1}$ to $\mathbb{D}$ belong to certain subclasses of univalent functions. The bounds obtained improve some existing known bounds.
