Euler–Poincaré Reduction on Principal Bundles

  • M. Castrillón López

Let π: PM be an arbitrary principal G-bundle. We give a full proof of the Euler–Poincaré reduction for a G-invariant Lagrangian L: J1P → R as well as the study of the second variation formula, the conservations laws, and study some of their properties.
