TL;DR: By means of contour integrals involving arbitrary analytic functions, general solutions of the zero-rest mass field equations in flat space-time can be generated for each spin this article.
Abstract: By means of contour integrals involving arbitrary analytic functions, general solutions of the zero‐rest‐mass field equations in flat space‐time can be generated for each spin. If the contour surrounds only a simple (respectively, low‐order) pole of the function, the resulting field is null (respectively, algebraically special).

TL;DR: In this article, it was shown that the 10 gravitationallyconserved quantities defined in asymptotically flat, empty, space times are, when suitably modified, also conserved in space-time Einstein-Maxwell space times.
Abstract: It is shown that the 10 gravitationally‐conserved quantities defined in asymptotically flat, empty, space‐times are, when suitably modified, also conserved in asymptotically flat Einstein‐Maxwell space‐times. Furthermore, the implied selection rules for transitions between stationary Einstein‐Maxwell states are the same as those in the pure gravitational case.
