E. Caglioti et C. Marchioro, Bounds on the growth of the velocity support for the solutions of the Vlasov-Poisson equation in a torus, J STAT PHYS, 100(3-4), 2000, pp. 659-677
A bound on the growth of the velocity for the Vlasov-Poisson equation in a
torus is given in one and two dimensions. The main tool used in the proof i
s a partition into fast and slow particles and the ergodic property of the
free motion in a torus.
