Homework Help: Working out a Second Class Constraint in Gory detail?

  1. Nov 28, 2006 #1

    I've been fooling around with some equations, and I've managed to land a second class constraint (I don't know whether to laugh or cry). Well, I was wondering is there any good introduction to the subject?

    The problem I have is that I made the conjugate momentum a function of position, so I have the constraint:
    C^i = \pi^i - p^i = 0
    and thus
    [C^i, C^j] \neq 0
    and I would like to know what exactly [C^i, C^j] is equal to; however, I've never really learned quantum field theory "traditionally" and so I'm completely stuck.

    Any help would be greatly appreciated!

    If i don't know who [itex] \pi^{i} [/itex] and [itex] p^{i} [/itex] are, i can't really help you.


    P.S. It's enough to post the lagrangian (density) you started with.

    Well, I think I've got it figured out now, thanks anyways.
