Shortest closed curve to contain a sphere in its convex hull

M Ghomi, J Wenk - Bulletin of the London Mathematical Society, 2024 - Wiley Online Library
We show that in Euclidean 3‐space any closed curve which contains the unit sphere within
its convex hull has length L⩾ 4 π L\geqslant4π, and characterize the case of equality. This …

A nearly tight lower bound for the d-dimensional cow-path problem

N Bansal, J Kuszmaul, W Kuszmaul - Information Processing Letters, 2023 - Elsevier
In the d-dimensional cow-path problem, a cow living in R d must locate a (d− 1)-dimensional
hyperplane H whose location is unknown. The only way that the cow can find H is to roam R …
