On the radius of analyticity and Gevrey regularity for the Boltzmann equation
Wei-Xi Li, Lvqiao Liu, Hao Wang
This paper investigates the non-cutoff Boltzmann equation for hard potentials in a perturbative setting. We first establish a sharp short-time estimate on the radius of analyticity…

Gevrey regularity of mild solutions to the non-cutoff Boltzmann equation
Renjun Duan, Wei-Xi Li, Lvqiao Liu
In the paper, for the Cauchy problem on the non-cutoff Boltzmann equation in torus, we establish the global-in-time Gevrey smoothness in velocity and space variables for a class of…
