| dc.description | An alternative derivation of general relativity is presented in which the field equations are derived from a gauge invariant quadratic Lagrangian by varying the affine field Gamma <sub>bc</sub><sup>a</sup> and keeping the geometry fixed. The field equations show that the Gamma <sub>bc</sub><sup>a</sup> can be considered as a Christoffel connection of a tensor g<sup>ab</sup> and if, after the variation, the metric tensor is chosen to be this tensor, the field equations of general relativity with a cosmical constant are recovered. |
