Hi all-
On non-unique theories. Question is, what do you mean by
"mathematically equivalent". Take electrodynamics in two different gauges.
Are the two formulations "mathematically equivalent"? We know that they
ar e physically equivalent because they make identical predictions about
physics.
Another case in point, is Hamiltonian mechanics "mathematically
equivalent" to Newtonian mechanics? What is your criterion?
Regards,
Jack
