mathematical theory of collision processes in (dilute) gases and plasmas, viewed as a …

On a new class of weak solutions to the spatially homogeneous Boltzmann and Landau equations

C Villani - Archive for rational mechanics and analysis, 1998 - Springer
This paper deals with the spatially homogeneous Boltzmann equation when grazing
collisions are involved. We study in a unified setting the Boltzmann equation without cut-off …

On the Cauchy problem for Boltzmann equations: global existence and weak stability

RJ DiPerna, PL Lions - Annals of Mathematics, 1989 - JSTOR
We study the large-data Cauchy problem for Boltzmann equations with general collision
kernels. We prove that sequences of solutions which satisfy only the physically natural a …

On the trend to global equilibrium for spatially inhomogeneous kinetic systems: the Boltzmann equation

L Desvillettes, C Villani - Inventiones mathematicae, 2005 - Springer

equations, started in [21], we derive estimates on the rate of convergence to equilibrium for …

The Navier–Stokes limit of the Boltzmann equation for bounded collision kernels

F Golse, L Saint-Raymond - Inventiones mathematicae, 2004 - Springer
The present work establishes a Navier–Stokes limit for the Boltzmann equation considered
over the infinite spatial domain R 3. Appropriately scaled families of DiPerna-Lions …

Exponential decay for soft potentials near Maxwellian

RM Strain, Y Guo - Archive for Rational Mechanics and Analysis, 2008 - Springer
We consider both soft potentials with angular cutoff and Landau collision kernels in the
Boltzmann theory inside a periodic box. We prove that any smooth perturbation near a given …

Quantitative perturbative study of convergence to equilibrium for collisional kinetic models in the torus

C Mouhot, L Neumann - Nonlinearity, 2006 - iopscience.iop.org
For a general class of linear collisional kinetic models in the torus, including in particular the
linearized Boltzmann equation for hard spheres, the linearized Landau equation with hard …

Classical solutions to the Boltzmann equation for molecules with an angular cutoff

Y Guo - Archive for rational mechanics and analysis, 2003 - Springer
An important class of collision kernels in the Boltzmann theory are governed by the inverse
power law, in which the intermolecular potential between two particles is an inverse power …

Almost exponential decay near Maxwellian

RM Strain, Y Guo - Communications in Partial Differential …, 2006 - Taylor & Francis
By direct interpolation of a family of smooth energy estimates for solutions near Maxwellian
equilibrium and in a periodic box to several Boltzmann type equations in Guo () and Strain …
