Description: Dispersion relation serves as a base for all the Landau damping theory. In this paper we rederive the dispersion relation for general oscillator systems from a different approach which hopefully gives a little clearer view of the problem. Stability criteria are obtained by mapping technique. Two examples will be discussed to illustrate the sufficient condition for stability. 5 refs., 3 figs.
