    "abstract": "The gyrokinetics formulation of plasmas in strong magnetic fields aims at the\nelimination of the angle associated with the Larmor rotation of charged\nparticles around the magnetic field lines. In a perturbative treatment or as a\ntime-averaging procedure, gyrokinetics is in general an approximation to the\ntrue dynamics. Here we discuss the conditions under which gyrokinetics is\neither an approximation or an exact operation in the framework of reduction of\ndynamical systems with symmetry",
