Hello,(adsbygoogle = window.adsbygoogle || []).push({});

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!
