Abstract
In the context of a recently proposed GL(4)-invariant formulation of general relativity the authors discuss a generalized Palatini formalism in which the conditions of metricity and torsionlessness are both obtained as dynamical equations. This theory can be reformulated in terms of new variables which, in a special gauge, reduce to the ones introduced by Ashtekar (1987,8). They describe the emergence of the new variables both in Lagrangian and in Hamiltonian language.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
