We provide some new explicit expressions for the linearized non-cutoff radially symmetric Boltzmann operator with Maxwellian molecules, proving that this operator is a simple function of the standard harmonic oscillator. A detailed article is available on arXiv [15].
An overview of recent results pertaining to the hydrodynamic description (both Newtonian
and non-Newtonian) of granular gases described by the Boltzmann equation for inelastic
Maxwell models is presented. The use of this mathematical model allows us to get exact
results for different problems. First, the Navier–Stokes constitutive equations with
explicit expressions for the corresponding transport coefficients are derived by applying
the Chapman–Enskog...
This note is an announcement of a forthcoming paper [13] in collaboration with K. Pravda-Starov on global hypoelliptic estimates for Fokker-Planck and linear Landau-type operators. Linear Landau-type equations are a class of inhomogeneous kinetic equations with anisotropic diffusion whose study is motivated by the linearization of the Landau equation near the Maxwellian distribution. By introducing a microlocal method by multiplier which can be adapted to various hypoelliptic kinetic equations,...
