On a simplified description of waves in non-collision plasmas

Aim of this methodic note is to collate approaches of A.A. Vlasov and L.D. Landau to the propagation of electromagnetic waves in hot rarified plasmas. Over half a century ago, A.A. Vlasov and L.D. Landau used the kinetic equation to show that – in accordance to the causality principle – electromagnetic waves propagating in equilibrium plasmas should decay even if the binary interaction between particles is negligibly weak. However, for a long time, the pioneer theories of A.A. Vlasov and L.D. Landau were regarded as not quite congenial.
