Non-exact solutions in general relativity

Non-exact solutions in general relativity

Non-exact solutions in general relativity are solutions of Albert Einstein's field equations of general relativity which hold only approximately. Common examples are the solutions to the linearized equations which are derived by letting the components gμν of the metric equal the components ημν of the flat Minkowski metric plus a small perturbation hμν, and then dropping all terms which are of second or higher order in hμν.
