evidence: Non-exact solutions in general relativity are solutions of Albert Einstein 's field equations of general relativity which hold only approximately .. solutions. Solutions of the Einstein field equations. field equations of general relativity. Einstein field equations. These solutions are typically found by treating the gravitational field , , as a background space-time , , -LRB- which is usually an exact solution -RRB- plus some small perturbation , .. solutions. Solutions of the Einstein field equations. Then one is able to solve the Einstein field equations as a series in , dropping higher order terms for simplicity .. Einstein field equations. Einstein field equations. series. Power series solution of differential equations. A common example of this method results in the linearised Einstein field equations .. Einstein field equations. Einstein field equations. linearised Einstein field equations. linearised Einstein field equations. In this case we expand the full space-time metric about the flat Minkowski metric ,  :. Minkowski metric. Minkowski metric. and dropping all terms which are of second or higher order in .
