LeanPool.PoincareThreeBody.CollisionBandObstruction

The leading obstruction on collision-band resonances #

Fiberwise density in eccentricity propagates each collision-band resonant obstruction from the nondegenerate eccentricities to every admissible eccentricity at that resonance.

@[reducible, inline]

Interior first actions whose semimajor axis lies in the collision band.

      Collision-band resonances are dense, so the leading wedge vanishes throughout the band at every fixed admissible eccentricity.
