 Hello,
I am a beginner for this package. How to use metric in ADM form in xPand ?

Hi,

I'd recommend to look at section 7.8 of xTensorDoc.nb, on induced metrics. That explains the general approach to ADM decompositions in xAct.

Then, try to attack your problem with that machinery, and the extensions in xPand. If you get stuck, ask again.

Cheers,
Jose.
