Abstract
By using the Hamilton-Jacobi (HJ) framework the three-dimensional Palatini theory plus a Chern-Simons term (PCS) is analyzed. We report the complete set of HJ Hamiltonians and a generalized HJ differential from which all symmetries of the theory are identified. Moreover, we show that despite PCS Lagrangian produces Einstein’s equations, the generalized HJ brackets depend on a Barbero-Immirzi-like parameter. In addition we complete our study by performing a canonical covariant analysis, and we construct a closed and gauge invariant two-form that encodes the symplectic geometry of the covariant phase space.
