Solutions of the ZeroRestMass Equations
Abstract
By means of contour integrals involving arbitrary analytic functions, general solutions of the zerorestmass field equations in flat spacetime can be generated for each spin. If the contour surrounds only a simple (respectively, loworder) pole of the function, the resulting field is null (respectively, algebraically special).
