Aug 30, 2023 at 1:01 comment added Willie Wong I used the square because that's what is used in the original question. @shuhalo Your question is probably better directed to the OP.
Aug 29, 2023 at 15:38 comment added shuhalo Is there a specific reason why one would use the squares of the distance functions rather than the distance functions themselves?
Aug 24, 2023 at 22:50 comment added shuhalo This has kept me busy for a day. The Lipschitz constant can also be written $6 \sqrt{N} / \delta_1$, which looks like a much better upper bound than what the published literature. Then it finally dawned on me that $\delta_1$ is quite a conservative lower bound for the Lebesgue number. It may generally only be the $N$-th part of the best possible Lebesgue number $\delta_\ast$. The best known bounds actually scale like $N / \delta_\ast$.
