An introduction to functional methods for many-body Green functions / L.G. Molinari. ((Intervento presentato al convegno Green's function methods : the next generation tenutosi a Toulouse nel 2013.
Abstract:
This is an introduction to the coherent-state representation of the generating functional of correlators for fermions. Ward's identities, Dyson's equations, and the effective potential are discussed for systems of electrons with Coulomb interaction.
