Gravity & Electromagnetism On The Null Cone, Maria Babiuc-Hamilton
Maria C. Babiuc-Hamilton
Gravitational and electromagnetic radiation travel along light rays, which are principal null directions in space-time. They are characteristic surfaces of Einstein and Maxwell equations. In characteristic coordinates, the field is described by ordinary differential equations.
