			Using these assumptions one can construct an [[effective field theory]] in low energies for both. In this form the action of general relativity can be written in the form of the '''Plebanski action''' which can be constructed using the [[Palatini action]] to derive [[Einstein's field equations]] of [[general relativity]].

			The form of the action introduced by [[Jerzy Plebański\|Plebanski]] is:

			:<math>S_{Plebanski} = \int_{\Sigma \times R} \epsilon_{ijkl} B^{ij} \wedge F^{kl} (A^i_a) + \phi_{ijkl} B^{ij} \wedge B^{kl} </math>

			where

			:<math>i, j, l, k</math>

			are internal indices,

			:<math>F</math>

			is a curvature on the orthogonal group <math>SO(3, 1)</math> and the [[Connection (mathematics)\|connection]] variables (the gauge fields) are denoted by

			:<math>A^i_a</math>.

			The symbol

			:<math>\phi_{ijkl}</math>

			is the [[Lagrangian multiplier]] and

			:<math>\epsilon_{ijkl}</math>

			is the [[antisymmetric symbol]] valued over <math>SO(3, 1)</math>.

			The specific definition

			:<math>B^{ij} = e^i \wedge e^j</math>,

			which formally satisfies the [[Einstein's field equation]] of [[general relativity]].
