Abstract:
We prove that the four-momentum of the electromagnetic field of a point charge is a four-vector if the field Lagrangian is nonlinear (with respect to field invariants) and the field mass is finite. We define the class of Lagrangians leading to a bound on the field mass.
Keywords:
nonlinear electrodynamics, point charge, field mass, field four-momentum.
