Entropy–entropy production conjecture. There exists $\lambda_{\gamma,b}>0$ such that

The linearized Burnett system is considered in the BGK setting, where the temperature coupling back to the velocity dynamics has the opposite sign from the stable BGK case. Tempera…

Let $G=\{x\in U:r(x)>0\}$ be a domain with $r\in C^1(U)$, smooth noncharacteristic boundary away from the grazing set, and suppose the transport problem … has homogeneous inflow da…

Let $G=B(0,R)\subset\mathbb{R}^3$, let $S$ be the sphere of transport directions, and let $I^\circ$ denote the interior of the energy interval. Consider the solution…
