Parameter-Space Heat Flow, Gaussian Density Ratios, and Sharp Hermite Truncation Rates
Jae Wan Shim
We reinterpret the classical Hermite generating function as a Gaussian density ratio: relative to the unit Gaussian reference, it is the density ratio of a Gaussian with shifted me…

Conductive Heat Flux Driven by a Pressure Gradient in Non-Maxwellian Reference States
Jae Wan Shim
Standard Navier--Stokes--Fourier theory and Maxwellian-based Grad 13-moment closures yield no independent pressure-gradient driving of the conductive heat flux in an isothermal, si…
