Physical Review D, 103 (2), 0240512470-0010https://hdl.handle.net/10016/32256We discuss a simple symplectic formulation for tetrad gravity that leads to the real Ashtekar variables in a direct and transparent way. It also sheds light on the role of the Immirzi parameter and the time gauge.5eng© 2021 American Physical Societyresearch articleMaterialeshttps://doi.org/10.1103/PhysRevD.103.024051open access0240512Physical Review D103AR/0000026830
