广义相对论中流动的Anderson-Witting输运系数
Anderson-Witting transport coefficients for flows in general relativity
摘要：
在广义相对论中，导出了由相对论Boltzmann方程中碰撞项的Anderson-Witting近似引起的近平衡流的输运系数。使用四元组形式主义，它表明，这些系数的表达式是相同的平坦的时空，在协议的广义等效原理。
英文摘要：
The transport coefficients induced by the Anderson-Witting approximation of the collision term in the relativistic Boltzmann equation are derived for close to equilibrium flows in general relativity. Using the tetrad formalism, it is shown that the expression for these coefficients is the same as that obtained on flat space-time, in agreement with the generalized equivalence principle.
