摘要：

From the freedom exhibited by the generalized Einstein action proposed in Dubois-Violette and Lagraa (2010 Lett. Math. Phys. 91 83-91), we show that we can construct the standard effective Einstein-Cartan action coupled to the fermionic matter without the usual current-current interaction and therefore an effective action which does not depend either on the Immirzi parameter or on the torsion. This establishes the equivalence between the Einstein-Cartan theory and the theory of general relativity minimally coupled to the fermionic matter.
