Rate of convergence of the Kac particle system for the Boltzmann equation with hard potentials
Chenguang Liu, Liping Xu, An Zhang
In this paper, we prove that the Kac stochastic particle system converges to the weak solution of the spatially homogeneous Boltzmann equation for hard potentials and hard spheres.…
