| Oct 5, 2015 at 6:45 | comment | added | pageman | Here's a post by Terence Tao on this conjecture: terrytao.wordpress.com/2015/05/13/… | |
| Jul 2, 2012 at 2:14 | comment | added | Andrew Dudzik | This is open for $k\geq 7$. The proof for $k=6$ was done by Barajas and Serra using elaborate computer-assisted casework, and many simplifications that rely on the fact that $6+1$ is prime. It is worth noting that when the ratio of two speeds is irrational, the problem is made easier by density arguments, so the essentially hardest case is when all the speeds are integers. Therefore this is a combinatorial number theory question disguised as basic calculus. | |

| Jun 22, 2012 at 18:59 | comment | added | Gerhard Paseman | Also, I suspect this is equivalent to the lonely starting post conjecture, which is the conjecture above except that one of the runners has speed 0 and the statement is that he/she gets lonely.
