introduction
- can be formulated using classical fields and lagrangian density
- change the coordinates and fields accordingly
- require the invariance of action integral over arbitrary region
- this invariance consists of two parts : Euler-Lagrange equation and the equation of continuity
Euler-Lagrange equation
- if field satisfies the equation of motion, EL is satisfied
equation of continuity
- current density \(J_{\mu}\) satisfies
\(\partial^{\mu} J_{\mu}=0\) - we get a conserved quantity
\(G:=\int_V J_0(x) \,d^3 x\) - Lagrangian can be used to express the current density explicity
