The general problem of representing the Greens function G(k,z) in terms of self-energy in field theories lacking Wick’s theorem is considered. A simple construction shows that a Dyson-like representation with a self-energy !(k,z) is always possible, provided we start with a spectral representation for G(k,z) for finite-sized systems and take the thermodynamic limit. The self-energy itself can t...
