摘要
本文引入了E中r阶空间角的概念,建立了有限向量集的一类三角不等式.作为其应用,得到了n维单形的两类三角不等式,推广和改进了一些已有文献中的主要结果.
In this paper Y the concept of space angle of order r in E' is introduced f a class oftriangle inequalities of a finite vector set are established, as their applicatios, two classes oftriangle inequalities on n-simplex are got, the main results of in reference are generalized andimpro ved.
