Summary
Differences between scalar field and scalar density solutions are explored using a Robertson–Walker (RW) metric, and a nonrelativistic Hamiltonian is derived for a scalar density field in the post-newtonian approximation. The results are compared with those of a scalar field. The expanding universe in a RW metric and a post-newtonian solution of the Klein–Gordon equation are discussed separately.
