The stability of charged solitons described by the relativistic complex scalar field is investigated by the direct Lyapunov method. It is shown that the stability of pulson-type solitons can only be conditional. Some necessary and sufficient conditions for the stability of stationary solitons with fixed charge are established. Several examples are considered. © 1980 Plenum Publishing Corporation.
