论文摘要
我们调查了几个与简单球的数量,邻居简单球的数量,中央对称的简单球的数量以及CS-Neighborly的中央对称性较小球的数量以及由Simplecicial SpherES产生的超透明的横向数量有关的几个新旧问题。
We survey several old and new problems related to the number of simplicial spheres, the number of neighborly simplicial spheres, the number of centrally symmetric simplicial spheres that are cs-neighborly, and the transversal numbers of hypergraphs that arise from simplicial spheres.
