Some Exact Solutions of the Field Equations of General Relativity

Abstract

A method for generating nonstatic solutions of the Einstein‐Maxwell field equations in vacuo from nonstatic solutions of the empty space‐time field equations is given. It is shown that under certain conditions one of the metrics under investigation admits algebraically degenerate vacuum solutions. The necessary and sufficient condition in order that the vacuum solutions for this metric be of type null is obtained. Some exact solutions are listed.
