来源于:arXiv
In this paper, we extend the geometric concept of linearity to betweenness
structures, suitable combinatorial abstractions of finite metric spaces. As our
main result, we prove that every linear betweenness structure is induced by
either a path (of length $n$) or a cycle of length 4. 查看全文>>
