Neighborly spheres and transversal numbers
Isabella Novik, Hailun Zheng · arXiv (Cornell University) · 2022
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.
