SUMMARY:Another Afternoon of Fluid Dynamics: Dowan Koo (University of Oxfor
 d)
DESCRIPTION:We establish the global existence of Lagrangian solutions to th
 e ionic Vlasov-Poisson system for a broad class of initial data. The key i
 ngredient is a new decomposition of the electric potential for the Poisson
 -Boltzmann equation\, which yields quantitative a priori estimates and sta
 bility properties under L^p physical densities with p>1\, whereas previous
  approaches require p>d/2. Based on these estimates\, we establish stabili
 ty of the associated flows and construct global Lagrangian solutions. Base
 d on a joint work with Young-Pil Choi and Sihyun Song (Yonsei University).
