Abstract
A new approach to the study of the dynamical evolution of planetary ri ngs and similar objects is developed. A Boltzmann equation with a coll isional term is used as an initial approximation. The case of relative ly rare collisions is examined. It is shown that the system tends towa rd either a fundamentally three-dimensional or a perfectly flat config uration, depending on the coefficient of inelasticity of the collision s.
