The evolution of planetesimal swarms in unperturbed regions of the solar nebula have been modeled extensively by both n-body simulations and by kinetic theory. The dynamics of planetesimal swarms that are resonantly perturbed by a distant planet are not so well understood, in spite of numerous studies of resonantly perturbed planetary rings. The published work on planetary rings is not directly relevant to planetesimal swarms because planetary ring models assume moderate to large collision frequencies that tend to damp out the nonlinear dynamics of resonant orbits. Alternatively, the collective self-gravity in planetary rings is assumed to be strong enough to excite spiral density waves that can also suppress the nonlinear dynamics of resonant orbits. However, planetesimal swarms in the asteroid belt and in the outer solar system that were resonantly perturbed by Jupiter most likely had very small collision frequencies and minimal collective self-gravity. Thus, whereas resonances in planetary rings exhibit orbital eccentricities that are linearly proportional to the mass of the perturbing moon, resonances in planetesimal swarms exhibit orbital eccentricities that are proportional to the cube root of the mass of the perturbing planet.
