On Codimension one Embedding of Simplicial Complexes
Anders Björner, Afshin Goodarzi · arXiv (Cornell University) · 2016
We study $d$-dimensional simplicial complexes that are PL embeddable in $\mathbb{R}^{d+1}$. It is shown that such a complex must satisfy a certain homological condition. The existence of this obstruction allows us to provide a systematic approach to deriving upper bounds for the number of top-dimensional faces of such complexes, particularly in low dimensions.
