Derivation of the Boltzmann equation from hard-sphere dynamics (after Y. Deng, Z. Hani, and X. Ma)
Thierry Bodineau, Isabelle Gallagher, Laure Saint-Raymond +1
Consider a microscopic system of hard spheres that are initially independent (modulo the exclusion condition on particle positions) and identically distributed in $\mathbb{R}^3…

Pointwise decay of truncated correlations in chaotic states at low density
Andrea Di Stefano, Sergio Simonella, Raphael Winter
We study simple nonequilibrium distributions describing a classical gas of particles interacting via a pair potential , in the Boltzmann-Grad scaling .…
