Summary:: Pretty sure they have something to do with path integrals, or what not. But obviously it's hard to *search* for this stuff.
Basically, I'm looking for a textbook, any textbook--physics, mathematics, etc.--that deals with integrals that look something like this (mistakes are mine):
S = \int dx^4 \Omega \, e^{i \int \mathcal{L} dt}
Where S is an action to be minimized, \Sigma is just something integrable across the 4-volume and \mathcal{L} is a Lagrangian. Ideally, looking for something that:
1. explains why the Lagrangian is in the exponent of e like that and what it signifies, and
2. works an example of minimizing S.
Basically, just want to know where to start.
