- How to work with metrics when solving a problem that is inherently limited to the second order in one parameter?
I use metric, which describes spacetime upto second order terms in rotation. It is solution of Einstein equations expanded upto second order. My query is, how to manipulate with such metric during calculations? Concetrly I make inverse metric, produce effective potential (ie, multiplying, makeing square root of coefficients etc.). Finally, I use it in numerical solution of Hamilton equations. What is appropriate procedure to hadle with this problem? Shall I expand upto second order all function after every calculation? Or...?
Thank you for any suggestion.
