WebIn this situation, the WZ variables are only auxiliary tools that permit to reveal the hidden symmetries present in the original second class model. We apply this formalism to important physical models: the reduced-SU(2) Skyrme model, the Chern-Simons-Proca quantum mechanics and the chiral bosons field theory. WebIndeed, the second Chern class cannot be a topological invariant in two dimensions. This class is represented by a rank $4$ form on smooth manifolds, thus its associated …
