Abstract
A fully nonlinear, time-asymptotic theory of nonlinear Landau damping and r esonant particle trapping in finite-amplitude waves is presented. The viria l theorem and the conservation of the parallel adiabatic invariant are used to determine the time-asymptotic distribution function. The effect of trap ped particles on the nonlinear wave dynamics is highly nontrivial and force s a significant departure from the conventional models of finite-amplitude waves.
