Abstract

Longitudinal oscillations in a relativistic plasma are studied. First a three-dimensional space + time approach (which is not manifestly covariant) is used. An approximate evaluation of the dispersion relation for the case of a weakly-relativistic plasma is then made. The problem of two-stream instability in a relativistic plasma is discussed, and the relativistic effects are shown to have a stabilising nature on the problem. Next, these treatments are repeated using a manifestly-covariant four dimensional space-time approach, and attention is drawn to discrepancies in the results deduced by these two approaches.
