Hi,
I would like to show explicitly the following identity for N = 2
are complex Grassmann Numbers.
are the complex conjugated of .
A is a hermitian matrix.
With I got:
Expansion
gives
Now I don't know, how to go on. I know that and the integral over 1 vanishes.
But this doesn't help me enough to continue the proof.
Could anybody help me with this?
Regards,
