爱因斯坦方程与引力场的能量密度
The Einstein equation and the energy density of the gravitational field
摘要:
我们推导出引力的爱因斯坦方程,它采用了引力场的局部能量密度作为对称的二阶张量的定义,其值为每个观察者给出了该观察者所看到的能量应力张量的空间部分的轨迹。我们使用轻压力给出了这种选择的物理动机。
英文摘要:
We give a derivation of the Einstein equation for gravity which employs a definition of the local energy density of the gravitational field as a symmetric second rank tensor whose value for each observer gives the trace of the spatial part of the energy-stress tensor as seen by that observer. We give a physical motivation for this choice using light pressure.
