Strict ordering conjecture for billiard winding numbers in ellipsoids
Let be the winding numbers of a periodic billiard trajectory inside an ellipsoid, as defined by the oscillations of its elliptic coordinates. Winding-number ordering conjecture. Winding numbers are always ordered in a strict decreasing way:
This conjecture was stated in earlier work and tested numerically. The supplied text gives no resolution, so its general status remains open.
