关于内心单形的一个猜想

A conjecture for the incenter simplex

利用距离几何的理论和方法证明了关于内形单形的一个猜想 ,同时放宽了该猜想所述不等式取等号的充要条件 .

In this paper,a conjecture for the incenter simplex is proved,using the principle and method of distance geometry.Meanwhile,a necessary and sufficient condition,of which equality holds,is obtained with respect to the above conjecture.
