Canonical form of Euler-Lagrange equations and gauge symmetries
B. Geyer, D. M. Gitman, I. V. Tyutin
The structure of the Euler-Lagrange equations for a general Lagrangian theory is studied. For these equations we present a reduction procedure to the so-called canonical form. In t…

Hamiltonization of theories with degenerate coordinates
D. M. Gitman, I. V. Tyutin
We consider a class of Lagrangian theories where part of the coordinates does not have any time derivatives in the Lagrange function (we call such coordinates degenerate). We advoc…
