SUMMARY:Seminar Analysis and Mathematical Physics: Klaus Widmayer (Universi
 tät Zürich)
DESCRIPTION:While "Landau damping" is regarded as an important effect in th
 e dynamics of hot\, collisionless plasmas\, its mathematical understanding
  is still in its infancy. This talk presents a recent nonlinear stability 
 result in this context. Starting with a discussion of stabilizing mechanis
 ms in the linearized Vlasov-Poisson equations near a class of homogeneous 
 equilibria on R^3\, we will see how both oscillatory and damping effects a
 rise\, and sketch how these mechanisms imply a nonlinear stability result 
 in the specific setting of the Poisson equilibrium. This is based on joint
  work with A. Ionescu\, B. Pausader and X. Wang.
