Characterization of gravitational radiation at infinity with a cosmological constant
Abstract
Abstract The existence or absence of gravitational radiation escaping from the space time at J is characterized in the presence of a cosmological constant Λ of any sign. To that end, the properties of the asymptotic super-momentum are used. When Λ = 0, the characterization is equivalent to that based on the News tensor. For Λ ≠ 0, it provides the first reliable definition of existence of radiation at J , and it gives fully satisfactory results in known exact solutions.
