| Aug 18, 2010 at 6:23 | comment | added | Gerry Myerson | @Yemon, I take it Richard is just assigning a number to each chord (namely, the cosine of the angle subtended by the chord) and then asking whether there must be a point such that the sum of the numbers assigned to the chords meeting at that point is at most minus one. Richard chooses to call that number a link weight, but a rose by any other name.... | |
