The Lonely Runner Conjecture for Nine and Ten Runners

partialconfidence 70%

VibeMathed reports this item as partial. VibeMath preserves that report as a source assertion and has not independently authored a plain-language mathematical explanation.

Precise statement

The Lonely Runner Conjecture of Wills and Cusick states that among $k+1$ runners at distinct constant speeds on a unit circle, each runner is at some time at distance at least $1/(k+1)$ from all others. Following Rosenfeld's computer-assisted proof for 8 runners, the paper refines his approach with a sieve and proves the cases of 9 and 10 runners.

The source statement is reproduced for indexing with attribution. Mathematical correctness requires domain-expert or mechanical review. VibeMath has not independently audited statement fidelity, correctness, priority, or novelty.
