Summary: | O184; The mid-facet of a simplex in n-dimensional Euclidean space which was introduced quite recently is an important geometric element.An analytic expression for the mid-facet area of a simplex is firstly given.In order to obtain the expression,the exterior differential method was presented.Furthermore,the properties of the mid-facets of a simplex analogous to median lines of a triangle(such as for all mid-facets of a simplex,there exists another simplex such that its edge-lengths equal to these mid-facets area respectively,and all of the mid-facets of a simplex have a common point)were proved.Finally,by applying the analytic expression,a number of inequalities which combine edge-lengths,circumradius,median line,bisection area and facet area with the mid-facet area for a simplex were established. |
