Dimension-free estimates for covering functionals of simplices and $ℓ_{p}$ balls

Feifei Chen, Chan He, Senlin Wu

We study $Γ_{2^n}(K)$, the least positive number $γ>0$ such that an $n$-dimensional convex body $K$ can be covered by $2^n$ translates of $γK$. For $n$-simplices \(Δ_…

Homothetic covering of convex hulls of compact convex sets

Senlin Wu, Keke Zhang, Chan He

Let $K$ be a compact convex set and $m$ be a positive integer. The covering functional of $K$ with respect to $m$ is the smallest $λ \in [0, 1]$ such that $K$ can be covered by $m$ tr…
