CONCATENATING VARIATIONAL PRINCIPLES AND THE KINETIC STRESS-ENERGY-MOMENTUM TENSOR
Marco Castrillon Lopez, Mark J. Gotay & Jerrold E. Marsden
Abstract:
We show how to ``concatenate'' variational principles over different bases into one over a single base, thereby providing a unified Lagrangian treatment of interacting systems. As an example we study a Klein--Gordon field interacting with a mesically charged particle. We employ our method to give a novel group-theoretic derivation of the kinetic stress-energy-momentum tensor density corresponding to the particle.
