在本文中,我们将证明,如果一个封闭曲面的任意两个二部四边形具有相同且足够大的顶点数,则它们可以通过对角滑动和对角旋转相互转化,直至相等。同样,对于封闭曲面的三角剖分,我们也证明了同样的事实。
In this paper we shall show that any two bipartite quadrangulations of a closed surface can be transformed into each other by diagonal slides and diagonal rotations, up to isotopy, if they have the same and sufficiently large number of vertices. Also, we show the same fact for triangulations of a closed surface.
