제목: Global existence of Lagrangian solutions to the ionic Vlasov--Poisson system
초록: In this talk, we study the Cauchy problem of the ionic Vlasov--Poisson (IVP) system for a broad class of initial data. To this end, we establish well-posedness and stability estimates for the Poisson--Boltzmann equation $-\Delta \Phi = \rho -e^\Phi$ provided $\rho \in L_+^p$ with $p>1$, whereas previous approaches required $p>\frac{d}{2}$. Building upon these results, we construct global-in-time renormalized/Lagrangian solutions to the IVP system. Based on a joint work with Young-Pil Choi and Sihyun Song (Yonsei University).
