球面上的Erds-Mordell不等式

Erds-Mordell Inequality on Sphere in R^3

引进球面三角形的可行点的概念,把平面上的Erd¨os Mordell不等式推广到三维欧氏空间R3中的球面上.

In this paper, by using the concept of sphere triangle, Erds-Mordell inequality on the plane is generalized to a sphere in the 3-dimensional Euclidean space R^3,and a new inequality is established.
