加权GP猜想的外接三角形方法

The circumscribed triangle method in proof of the weighted Gilbert-Pollak conjecture

本文利用外接三角形方法，解决了第三种情况下的加权Ｓｔｅｉｎｅｒ问题，并给出三点加权ＧＰ猜想的简单证明．

In this paper, we solve the third case of the weighted Steiner problem by using the circumscribed triangle method, and give a simple proof for the 3-point case of the weighted Gilbert-Pollak conjecture.
