一个闭曲面上的四边形是极小的,如果它的最短不可收缩圈的长度是,如果任何面收缩产生一个长度小于的不可收缩圈。证明了正则2k边形的菱形镶嵌与射影平面及其指定的非收缩k-圈上的ak-极小四边形对双射对应。
A quadrangulation on a closed surface isk-minimal if its shortest noncontractible cycle is of lengthkand if any face contraction yields a noncontractible cycle of length less thank. We prove that the rhombus tilings of a regular 2k-gon bijectively correspond to the pairs of ak-minimal quadrangulations on the projective plane and its specified noncontractiblek-cycle.
