how to find the conserved generators expression?
« on: 21/08/2011 01:41:28 »
hello

1D. A is the action, and it is invariant under conform transformation G. Q is the field. G transform Q and t. 
now i have the next equation: 
variation(A)+integral (dt*(df(Q)/dt))=integral (dt*(dG/dt))=0
and i dont understand why this equation right and what f(Q) stand for.

thanks
