Routh reduction for first-order field theories

Mathematical Physics 2018-12-05 v2 math.MP

Abstract

We present a reduction theory for first order Lagrangian field theories which takes into account the conservation of momenta. The relation between the solutions of the original problem with a prescribed value of the momentum and the solutions of the reduced problem is established. An illustrative example is discussed in detail.
