Abstract
Effects induced by the finite number N of particles on the evolution of a monochromatic electrostatic perturbation in a collisionless plasma are investigated. For growth as well as damping of a single wave, discrete particle numerical simulations show a N-dependent long-time behavior which differs from the numerical errors incurred by Vlasovian approaches and follows from the pulsating separatrix crossing dynamics of individual particles.
