On Unavoidable Faces of High-Dimensional Polytopes

Jesús A. De Loera, Ethan X. Fang, Shengtao Guo +2

Kalai's cube--simplex conjecture asserts that for all positive integers $ℓ, k$ , there is an integer $f (ℓ, k)$ such that every polytope of dimension at least $f (ℓ, k)$ has eit…

Sharp Bounds on the Independence Number of Simplicial Spheres

Jesús A. De Loera, Ethan X. Fang, Junwei Lu +2

We study the maximum size of an independent set in the graph of a simplicial sphere. Let $β (d, n)$ denote this maximum over all simplicial $(d - 1)$ -spheres on $n$ vertices, and let $…
