摘要
在n维欧氏空间E^n中,一个有界凸体K的宽度是这样定义的:对于每个单位向量u,将K的一对与u垂直的支撑超平面之间的距离记作τ(K,u)。
Let w(△n) denote the width of a non-degenerate simplex △n in E' and r(△n) denote the inradius of the simplex.Then, in this paper, we prove the ine-qunlity as below:Theorem:The equality holds if and only if the simplex is regular.
