gauge symmetry
  همامونی ِ گز  
hamâmuni-ye gaz
Fr.: symétrie de jauge  

A principle underlying the quantum-mechanical description of the three non-gravitational forces. It allows a system to behave in the same way even
though it has undergone various transformations. The earliest physical theory which had a gauge symmetry was Maxwell’s electrodynamics.
