Covariant Form of The Inhomogeneous Wave Equation
See also: Covariant formulation of classical electromagnetismThe relativistic Maxwell's equations can be written in covariant form as
where J is the four-current
- ,
is the 4-gradient and the electromagnetic four-potential is
with the Lorenz gauge condition
- .
Here
- is the d'Alembert operator.

Famous quotes containing the words form, wave and/or equation:
“Upon the whole, necessity is something, that exists in the mind, not in objects; nor is it possible for us ever to form the most distant idea of it, consider’d as a quality in bodies. Either we have no idea of necessity, or necessity is nothing but that determination of thought to pass from cause to effects and effects to causes, according to their experienc’d union.”
