- Abstract
- It is discussed the understanding of the Landau theory of the wave damping of plasmas without collisions. We present arguments for the necessity to understand in such theory as a Landau contour only one contour among two of such counters which were used formerly in the original Landau paper. But this contour is not that is such widely named as Landau contour. For the other contour which is analogous to Sohotskii contour we find the place in the approximate analytic theory of the collisionless damping of plasma waves only when such contour permits to obtain the necessary analytic continuation and besides it in the quasistationary theory of the ion acoustic turbulence.
