... not hard to see that if A and B are operators whose commutator is a number a, then [A, B] = a, [A, B 2 ] = 2aB, [A, B 3 ] = 3aB 2 , . . . [A, B n ] = naB n−1 . Hence, J(x ), 1 i δ δJ(y ) n = ... both integrals are the same, which cancels the 1 /2! factor. Using similar arguments, the limits of both of the remaining time integrals can be extended to ±∞ yield...
