Momentum sections in Hamiltonian mechanics and sigma models
arXiv:1905.02434 · doi:10.3842/SIGMA.2019.076
Abstract
We show a constrained Hamiltonian system and a gauged sigma model have a structure of a momentum section and a Hamiltonian Lie algebroid theory recently introduced by Blohmann and Weinstein. We propose a generalization of a momentum section on a pre-multisymplectic manifold by considering gauged sigma models on a higher dimensional manifold.
