Abstract

Using the theory and method of distance geometry to study the problems of stability of geometric inequalities for an n-dimensional simplex in the Euclidean space.From the deviation regular metric of two simplexes,we proved four important geometric inequalities for an n-dimensional simplex are all stable,and gave the stability versions of these geometric inequalities for a simplex.
