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…

Quantitative propagation of chaos for the Boltzmann equation with moderately soft potentials
Chenguang Liu, Liping Xu, An Zhang
We study the Kac particle system associated with the spatially homogeneous Boltzmann equation with non-cutoff collision kernels in the moderately soft potential regime . We…
