Phys. Rev. D 76, 104040 (2007) [11 pages]Helical symmetry in linear systemsReceived 21 March 2007; published 27 November 2007 We investigate properties of solutions of the scalar wave equation and Maxwell’s equations on Minkowski space with helical symmetry. Existence of local and global solutions with this symmetry is demonstrated with and without sources. The asymptotic properties of the solutions are analyzed. We show that the Newman-Penrose retarded and advanced scalars exhibit specific symmetries and generalized peeling properties. © 2007 The American Physical Society URL:
