Modulated Gibbs Measure and Mean-Field Limit for 3D Vlasov--Poisson--Fokker--Planck Equations

Xuanrui Feng, Zhenfu Wang

We introduce a modulated Gibbs measure for the usual tensorized initial data for stochastic Newton's systems with singular repulsive interactions. Using the uniform-in- partitio…

Uniform-in-time relative entropy estimates for Kac's approximation of the Landau equation

Xuanrui Feng, Chenguang Liu, Zhenfu Wang

We prove uniform-in-time quantitative relative entropy estimates for Kac's particle approximation of the three-dimensional spatially homogeneous Landau equation for Maxwellian mole…

Kac's Program for the Landau Equation

Xuanrui Feng, Zhenfu Wang

We study the derivation of the spatially homogeneous Landau equation from the mean-field limit of a conservative -particle system, obtained by passing to the grazing limit on Ka…

Propagation of Chaos for 2D Log Gas on the Whole Space

Shuzhe Cai, Xuanrui Feng, Yun Gong +1

We derive the quantitative propagation of chaos in the sense of relative entropy for the first time for the 2D Log gas or the weakly interacting particle systems with 2D Coulomb in…

Relative Entropy Method for Particle Approximation of the Landau Equation for Maxwellian Molecules

José Antonio Carrillo, Xuanrui Feng, Shuchen Guo +2

We derive the spatially homogeneous Landau equation for Maxwellian molecules from a natural stochastic interacting particle system. More precisely, we control the relative entropy…
