Lagrangian Reduction on Homogeneous Spaces with Advected Parameters
arXiv:1408.3019 · doi:10.3842/SIGMA.2015.009
Abstract
We study the Euler-Lagrange equations for a parameter dependent -invariant Lagrangian on a homogeneous -space. We consider the pullback of the parameter dependent Lagrangian to the Lie group , emphasizing the special invariance properties of the associated Euler-Poincaré equations with advected parameters.
