Our analysis starts with the flat geometry, so-called Minkowski spacetime, and follows by further generalizations on specific spherically symmetric geometries whose metric elements describe solutions to the Einstein’s field equation. Next the relativistic models originated from the conservation form of the energy momentum tensor relation on these particular examples of spacetime geometries are presented. Finally we introduce certain properties of these models of interests and hence provide a conclusion including a comparison (both theoretically and numerically) of the models of related geometries.
