Description
Building on the BGK fixed-point approach of Evans and Menegaki, we study kinetic models for gases driven by a spatially varying heat bath. We extend this viewpoint using infinite-time maps and linear bath estimates to obtain existence and stability results for BGK and perturbative Boltzmann models. Computed stationary profiles illustrate how the resulting density and temperature fields respond to the imposed thermostat.
