In field theory, from a local Lagrangian it is possible to derive the phase space of the system. Roughly speaking, it represents the space of Cauchy data of the theory. Such space is equipped with a closed 2-form, whose kernel is often given by Hamiltonian vector fields generating (gauge) symmetries. The reduced phase space (RPS) is obtained as a symplectic manifold via quotienting the original phase space. In this talk, after a brief introduction and an example of RPS in a simple case, I will present the derivation (using a construction due to Kijowski and Tulcjiew) of the RPS of N=1 supergravity in dimension 4. If time allows, the corresponding BFV description is then carried out.''
