利用距离几何的理论与方法,研究了欧氏空间E^n中涉及两个单形棱长和体积的几何不等式问题,建立了涉及两个n维单形棱长与体积的两个几何不等式,推广了E^n中n维Pedoe不等式和彭-常不等式。
Using the theory and method of distance geometry,the problems about geometric inequalities for the edge-lengths and volumes of two n-dimensional simplexes in the Euclidean space E^n are studied.Two geometric inequalities for the edge-lengths and volumes of two n-dimensional simplexes are established,and the n-dimensional Pedoe inequality and Peng-Chang inequality are improved.
