Hi all,

I've got this problem (which is attached as q1.jpg).

I've tried to solve it, but I'm stuck... my solution is also attached (my_sol1.jpg).

PLS help me :-(

Thnx

In your derivation of the EOM, you got some indices wrong and forgot an A^μ. Maybe there are also sign or coefficient errors, haven't checked it in detail. I propose you to redo it in more detail.
For the next step, derive your EOM once and calculate ( θ η^{μν} - ε^{μνα} ∂_α ) J_ν using your EOM and the derived version, which should give you the left side.

Thanks! I'll try it...

Do I know you from somewhere ? ;-)

Don't know if I have seen you, but if you were born in 1986, that's possible ... you have a private message.
