摘要
利用pre-Schwarz导数范数的方法对Schwarz导数意义下区域的单叶性内径进行了研究,得到了区域Schwarz导数单叶性内径下界的3个一般性公式.
The inner radius of univalency of hyperbolic domains by sehwarzian derivative is studied by means of the norm of pre-Schwarzian derivative. Three general formulas for the lower bound on inner radius of univalence in the sense of schwarzian derivative are established.
