对弧长度之和相等的Minkowshi平面的一个特征

Study on characterization of sums of length of relative arcs with equivalent property in Minkowski plane

证明了在Minkowski平面的单位圆中,若任意一组Birkhoff正交的弦,所形成的相对弧的长度之和总相等,则这个Minkowski平面是内积空间.

This paper proves that Minkowski plane is an inner product space if the sums of the length of two groups of relative arcs that Biekhoff arthogonalizes with each other in the unit circle of the Minkowski plane is equivalent.
