"Nettet11. mai 2024 · This shows that equation (2.3) is equivalent to the standard BTE for stationary heat transport. Accordingly, we suggest equation (2.3) rather than equation (2.15) as the BTE for the GCE I. Correspondingly, equations (2.5) and (2.7) are better choices for the continuity and constitutive equations than equations (2.13) and (2.14). " - Linearized boltzmann transport equation
