n维伪流形的偶三角剖分

Even triangulations of n-dimensional pseudo-manifolds

J. Hyam Rubinstein, Stephan Tillmann

摘要:

本文引入了n维伪流形的偶三角剖分,并将偶三角剖分的组合学与伪流形的拓扑学联系起来。这是通过正规超曲面理论和某些对称表示的研究来完成的。在三维空间中,给出了有一个顶点或两个顶点的偶三角剖分存在的充要条件。对于哈肯n-流形,观察到非常短的层次之间的有趣的连接,甚至三角剖分。

英文摘要:

This paper introduces even triangulations of n-dimensional pseudo-manifolds and links their combinatorics to the topology of the pseudo-manifolds. This is done via normal hypersurface theory and the study of certain symmetric representation. In dimension 3, necessary and sufficient conditions for the existence of even triangulations having one or two vertices are given. For Haken n-manifolds, an interesting connection between very short hierarchies and even triangulations is observed.
