gauge transformation

[′gaj tranz·fər′mā·shən]
(electromagnetism)
The addition of the gradient of some function of space and time to the magnetic vector potential, and the addition of the negative of the partial derivative of the same function with respect to time, divided by the speed of light, to the electric scalar potential; this procedure gives different potentials but leaves the electric and magnetic fields unchanged.
(physics)
An alteration of the phase of the fields of a gauge theory as a function of space and time which does not alter the value of any measurable physical quantity.

CLASSICAL GAUGE CONDITIONS AND GAUGE TRANSFORMATIONS
In the present paper, we have introduced new gauge transformations that leave Maxwell's equations, Lorentz gauge and the continuity equations invariant.
We know that the electric and magnetic fields are invariant under the following gauge transformations
Now let us introduce new gauge transformations (NGTs) as follows
k] through local phase changes, we recall that the electromagnetic field is the gauge field which guarantees invariance of the Lagrangian density under space-time local U(1) gauge transformations, i.
It is the gauge field which guarantees invariance under space-local U(1) gauge transformations.
Let us do a calculus of variation on this integral to derive a variational equation by applying a gauge transformation on (24) as follows.
Under a gauge transformation (regarded as a change of coordinate) with gauge function a(z(s)) this coordinate is changed to another coordinate ([A'.
Then it can be shown that the differential is unchanged under a gauge transformation [59]:
These transformations are similar to gauge transformations endorse on the vector potential ([?
