摘要: It is shown that in the Hamiltonian description of a wide class gauge invariant Lagrangian systems there arise only primary and secondary constraints they are all first class. The explicit expressions for Poisson brackets obtained by introducing so-called “standard” extension functions originally defined on constraint surface to whole phase space.
