where:
* ''G''<sup>''μν''</sup> is the [[Einstein tensor]] (which is constructed from the metric)
* ''g''<sup>''μν''</sup> is the inverse of the [[Metric tensor (general relativity)metric tensor]]
* ''g'' = det(''g''<sub>''μν''</sub>) is the [[determinant]] of the metric tensor and is < 0. Hence its appearance as <math>g </math>.
* <math>,_{\alpha \beta} = \frac{\partial^2}{\partial x^{\alpha} \partial x^{\beta}}\,</math> are [[partial derivative]]s, not [[covariant derivative]]s.
* ''G'' is Newton's [[gravitational constant]].
