Covariant derivate of tensor itself

46 Views Asked by At

In the context of Higgs physics when solving the Euler-Lagrange equation I end up with derivatives like the following

$\frac{\partial A^\nu}{\partial A^\mu}$

$\frac{\partial A_\mu}{\partial A^\mu}$

Could someone explain to me how to resolve these?

--- Update -----

Further the following derivate occurs

$\frac{\partial (\partial^\mu A^\nu)}{\partial (\partial^\nu A^\mu)}$

This one is obviously much harder than the previous ones. While I feel like getting the clue for the previous ones, I have a hard time resolving this one. As far as I know the result should be a scalar, looking at the Indices.

---- Update 2 -----

For anyone interested, the answers for the first two can be found below. For the derivate introduced in the first update, I decided to change the indices in the Euler Lagrange equation leading to the derivate

$\frac{\partial (\partial^\mu A^\nu)}{\partial (\partial^{\nu^, } A^{\mu^,})}$

This can then be easily found to be

$\delta_{\nu^,}^\mu \delta_{\mu^,}^\nu$

Defined to give kronecker deltas.

The first is $\delta_\mu^\nu$ and the second contracts the indices to form the trace of the identity, yielding D, the space time dimension.
