Distances from the vertices of a regular simplex

Mowaffaq Hajja, Mostafa Hayajneh, Bach Nguyen, Shadi Shaqaqha

摘要:

如果$S$是$d$维欧几里得空间$\mathcal{E}$中边长为$a$的给定正则$d$ -单形,则距离$t_1$,$\cdots$,$\mathcal{E}$中任意一点的$t_{d+1}$与$S$的顶点之间的关系是优雅关系$$(d+1)\left( a^4+t_1^4+\cdots+t_{d+1}^4\right)=\left( a^2+t_1^2+\cdots+t_{d+1}^2\right)^2.$$。本文的目的是证明这是$t_1,\cdots,t_{d+1}.$之间唯一的关系。分析代数和几何

英文摘要:

If $S$ is a given regular $d$-simplex of edge length $a$ in the $d$-dimensional Euclidean space $\mathcal{E}$, then the distances $t_1$, $\cdots$, $t_{d+1}$ of an arbitrary point in $\mathcal{E}$ to the vertices of $S$ are related by the elegant relation $$(d+1)\left( a^4+t_1^4+\cdots+t_{d+1}^4\right)=\left( a^2+t_1^2+\cdots+t_{d+1}^2\right)^2.$$ The purpose of this paper is to prove that this is essentially the only relation that exists among $t_1,\cdots,t_{d+1}.$ The proof uses tools from analysis, algebra, and geometry.
