Abstract
It is shown that the Penrose criteria for the existence of unstable electrostatic oscillations of a Vlasov plasma can be derived simply from the energy‐momentum conservation laws applied to marginally unstable modes. These criteria also are obtained variationally as necessary conditions for instability by extremizing the possible motions which can convert kinetic energy into electric field energy.Keywords
