| Popis: | The method used by Petrov to obtain the first classification of vacuum space–times has since been overshadowed by methods which yield a finer classification based on principal null directions. It is shown that this finer classification can be expressed in Petrov’s terms and a simple algorithm is obtained for finding all repeated principal null directions by matrix methods. |
