Abstract. We consider the polaron model of the relativistic quantum electrodynamics with a fixed total momentum.
We analyze some properties of the ground state energy of the model, and show that the polaron model has a ground state under a condition which includes conditions for an infrared and an ultraviolet cutoff for photon momenta.
In particular, we show that the model with zero total momentum, a nonzero mass of the electron and an infrared cutoff has a ground state.
