Query: Equilibrium of a confined, randomly-accelerated, inelastic particle: Is
  there inelastic collapse?   We consider the one-dimensional motion of a particle randomly accelerated by
Gaussian white noise on the line segment 0<x<1. The reflections of the particle
from the boundaries at x=0 and 1 are inelastic, with coefficient of restitution
r. We have solved the Fokker-Planck equation satisfied by the equilibrium
distribution function P(x,v) with a combination of exact analytical and
numerical methods. Throughout the interval 0<r<1, P(x,v) remains extended, as
opposed to collapsed. The particle is not localized at the boundary. However,
for r<0.163 the equilibrium boundary collision rate is infinite, as predicted
by Cornell et al., and all moments of the velocity just after reflection from
the boundary vanish.
