Upcoming Talk




63. November 3rd, 2022, At 9:00 pm-10:00 pm Beijing time


Speaker: Mikaela Iacobelli(ETH Zurich)


Title: Stability and singular limits in plasma physics


Abstract: In this talk, we will present two kinetic models that are used to describe the evolution of charged particles in plasmas: the Vlasov-Poisson system and the Vlasov-Poisson system with massless electrons. These systems model respectively the evolution of electrons, and ions in a plasma. We will discuss the well-posedness of these systems, the stability of solutions, and their behavior under singular limits. Finally, we will introduce a new class of Wasserstein-type distances specifically designed to tackle stability questions for kinetic equations.
