Please teach me this:
For gauge symmetry fields,only one of any elementary subconfiguration of the whole configuration covers the all physics of the field.So we need to cut off the redundant configuration.It seem to me,in a loose sense,there is only one way to cut off the redundancy(the gauge fixing condition).But in fact,they use many gauge conditions(e.g for electromagnetic field),from which we could derive different laws.Do they exhaustively cut off all the redundant configuration,and so why they lead to different laws.
Thank you very much in advanced.
