多边形切片上Scott映射的纤维是翻转等价类

The fibres of the Scott map on polygon tilings are the flip equivalence classes

Karin Baur, Paul P. Martin

摘要:

我们关联链图平铺的表面标记点,推广斯科特的三角形的方法。因此,我们得到了一个映射,从曲面的平铺到边界分量上标记点的排列,{ \em Scott映射}。在磁盘的情况下(多边形平铺),我们证明了纤维的斯科特地图的翻转等价类。结果使我们能够考虑的图像的大小作为一个经典的组合问题的概括,因此,以确定在低排名的大小。

英文摘要:

We associate strand diagrams to tilings of surfaces with marked points, generalising Scott's method for triangulations of polygons. We thus obtain a map from tilings of surfaces to permutations of the marked points on boundary components, the {\em Scott map}. In the disk case (polygon tilings) we prove that the fibres of the Scott map are the flip equivalence classes. The result allows us to consider the size of the image as a generalisation of a classical combinatorial problem, and hence to determine the size in low ranks.
