J Dolbeault, C Mouhot, C Schmeiser - Transactions of the American …, 2015 - ams.org
We develop a new method for proving hypocoercivity for a large class of linear kinetic
equations with only one conservation law. Local mass conservation is assumed at the level …

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

L Desvillettes, C Villani - Inventiones mathematicae, 2005 - Springer
As part of our study of convergence to equilibrium for spatially inhomogeneous kinetic
equations, started in [21], we derive estimates on the rate of convergence to equilibrium for …

Global classical solutions of the Boltzmann equation without angular cut-off

P Gressman, R Strain - Journal of the American Mathematical Society, 2011 - ams.org

collision kernels derived by Maxwell in 1866 for the full range of inverse-power …

The vlasov-maxwell-boltzmann system near maxwellians

Y Guo - Inventiones mathematicae, 2003 - Springer
Perhaps the most fundamental model for dynamics of dilute charged particles is described
by the Vlasov-Maxwell-Boltzmann system, in which particles interact with themselves …

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 …

linearized Boltzmann equation for hard spheres, the linearized Landau equation with hard …

[PDF][PDF] A review of Boltzmann equation with singular kernels

R Alexandre - Kinet. Relat. Models, 2009 - researchgate.net
We review recent results about Boltzmann equation for singular or non cutoff cross-sections.
Both spatially homogeneous and inhomogeneous Boltzmann equations are considered …

The Boltzmann equation without angular cutoff in the whole space: I, Global existence for soft potential

R Alexandre, Y Morimoto, S Ukai, CJ Xu… - Journal of Functional …, 2012 - Elsevier
It is known that the singularity in the non-cutoff cross-section of the Boltzmann equation
leads to the gain of regularity and a possible gain of weight in the velocity variable. By …

Boltzmann diffusive limit beyond the Navier‐Stokes approximation

Y Guo - Communications on Pure and Applied Mathematics: A …, 2006 - Wiley Online Library
Given a normalized Maxwellian μ and n≥ 1, we establish the global‐in‐time validity of a
diffusive expansion (0.1)\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, F^ ε (t, x, v)=\mu+ μ\left {ε f_ 1 (t, x, v)+ ε^ 2 f_ 2 (t, x …
