New Photon Propagators in Quantum Electrodynamics
Giampiero Esposito
A Lagrangian for quantum electrodynamics is found which makes it explicit that the photon mass is eventually set to zero in the physical part on observational ground. It remains po…

Photon Green Functions in Curved Space-Time
Giuseppe Bimonte, Enrico Calloni, Luciano Di Fiore +3
Quantization of electrodynamics in curved space-time in the Lorenz gauge and with arbitrary gauge parameter makes it necessary to study Green functions of non-minimal operators wit…

Highlights of Symmetry Groups
Giampiero Esposito, Giuseppe Marmo
The concepts of symmetry and symmetry groups are at the heart of several developments in modern theoretical and mathematical physics. The present paper is devoted to a number of se…
