Scientific paper

The authors have obtained solutions from an N-body simulation and a collisionless Boltzmann simulation which predict the evolution of the same model galaxy. The principal interest was to compare the non-linear development of a bar instability. The authors find excellent agreement; in particular, the limiting amplitude of the bar differs by merely 2 per cent between the two calculations.
