一类四边形区域的单叶性内径

The Inner Radius of Univalency of a Class of Quadrilateral Domain

本文利用Leila Miller-Van Wieren的方法对四边形区域进行研究,得到了边长依次为,且有三个内角相等的凸四边形区域的单叶性内径,并且证明了这样的四边形区域都是Nehari圆.

By the method of Leila Miner-Van Wieren, we get the inner radius of univalency of the convex quadrilateral domain with the lengths of its sides form the sequence abba and three angles are the same . And we prove that the domain is a Nehari disk.
