xPPN: an implementation of the parametrized post-Newtonian formalism using xAct for Mathematica
Abstract We present a package for the computer algebra system Mathematica, which implements the parametrized post-Newtonian (PPN) formalism. This package, named xPPN, is built upon the widely used tensor algebra package suite xAct, and in particular the package xTensor therein. The main feature of x...
